what is the vapor pressure (in torr) of a subtance at 36 c, whose normal boiling point is 84 c and has a delta hvap of 22.1 kj / mo

Answers

Answer 1

The vapor pressure of a substance is 241 Torr that can be calculated using Clausius-Clapeyron relation.

The Clausius-Clapeyron relation is used to characterize a discontinuous phase transition between two phases of the same constituent such as ice. The plot is drawn between 1/T vs ln P.

This equation can be expressed as follows:

ln(P2/P1) = (-ΔHvap/ R)*((1/T2) - (1/T1))

Where T1 is initial temperature, in our case it is normal boiling point = 84oC = 357 K

T2 is final temperature, in our case it is 36oC = 309 K

We know that at normal boiling point the vapor pressure of the substance become equal to the atmospheric pressure = 1 atm.

So P1 = 1 atm. according to our approach to the question.

Now enthalpy of vaporization is given = 22.1 kJ = 22100 J

Now put it in Clausius Clapeyron equation and we will get

ln(P2/ 1 atm.) = (-22100 J / 8.314 J/K-mole)*((1/309 K) - (1/357 K))

P2 /0.317 atm=0.317 x 760 torr = 241 torr

Answers

The reaction is exergonic. that is the free energy change delta G for a reaction is -46.11 kJ/mol, the reaction is exergonic.

Chemical thermodynamics, exergonic reactions are chemical reactions in which the change in free energy is negative (there is a net release of free energy).

This shows the spontaneous reaction when the system is closed and the initial and final temperatures are the same.

Reactions can be endergonic or exergonic. Endergonic reactions require heat or energy input. The exergonic reaction is the opposite. it gives off heat. Answer and Explanation:

What is the difference between endothermic and exothermic reactions? How do they affect the enthalpy and the temperature of the system and the surroundings?

Answers

The enthalpy of a system refers to the heat content of the system. In an endothermic reaction, the enthalpy of the system increases because heat is being absorbed from the surroundings. In an exothermic reaction, the enthalpy of the system decreases because heat is being released to the surroundings.

The temperature of the surroundings can also be affected by endothermic and exothermic reactions. In an endothermic reaction, the temperature of the surroundings decreases because heat is being absorbed by the system. In an exothermic reaction, the temperature of the surroundings increases because heat is being released by the system.

In summary, endothermic reactions absorb heat and have a positive enthalpy change, while exothermic reactions release heat and have a negative enthalpy change. The temperature of the system and the surroundings will change in opposite directions in endothermic and exothermic reactions.

1. in this experiment, why 3-sulfolene was used instead of 1,3-butadiene? explain thoroughly for full credit.

Starting with solid 3-sulfolene and decomposing was easier than starting with gaseous 1,3-butadiene.

3-Sulfolene is used to produce 1,3-butadiene by decomposition with maleic anhydride in solution. The solution should be heated slightly to decompose all the sulfolene to butadiene which reacts with the anhydride.

Diene is produced in a reaction vessel by heating butadiene sulfone until it decomposes into 1,3-butadiene and sulfur dioxide.

Answers

2.17x10^-33kj/mol of energy is damaged by the photons which are caused by the light.

The Energy of Proton:

The energy of a photon has a direct relationship with the frequency of the photon. It can be defined as the energy a single photon carries.

The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength.

Given that:

The light lies between 445nm and 470nm. so the value of c is 15nm

wavelength=4577.5nm

If the photon's wavelength is known, the photon's energy can be calculated using the formula :

h is Planck's constant,h=6.626x10^-34  c is the speed of light and the wavelength of the radiation are all represented in the equation.

Answers

If the reaction occurs at 298K and 1 atmosphere of pressure, the work done by the CO₂ is -24.8 Joules.

How to calculate work (in joule) is done by the CO₂ if the reaction occurs at 298K and 1atm of pressure?

Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases do expansion or compression work with the equation W = - P * ΔV.

From the question given

molarity of (NaHCO₃) = 0.1m

Volume of NaHCO₃ (V) = 100ml * 10⁻³ L / 1 ml = 0.1L

T (temperature) = 298k

P (pressure) = 1atm

moles of NaHCO₃

= molarity * Volume in Liters

= 0.1m * 0.1L = 0.01L

NaHCO₃ + HCl -> CO₂ + H₂O + NaCl

moles of CO₂ = moles of NaHCO₃ * (coefficient of CO₂ / Coefficient of NaHCO₃)

= 0.01L * 1/1

= 0.01 mol (moles of CO₂)

so, initial moles of CO₂ = 0

final moles of CO₂ = 0.01mol (based from the calculation)

Δn 0.01 - 0 = 0.01mol

Now, let's use work formula (as mentioned above on explanation part)

Work = - P * ΔV

= - Δn * R *T

Where R = 8.314J / mol.K

= - ( 0.01mol * 8.314 J / mol*K * 298K)

= -24.8J

Therefore, the work done by the CO₂ on this 100ml solution is -24.8Joules.

how many moles of agcl(s) would form when 100. ml of 0.400 m agno3 is mixed with 90.0 ml of 0.250 m cacl2 ? g

Answers

100ml of 0.400 m AgNO3 and 90.0 ml of 0.250 m CaCl2 would combine to create 0.0225 moles of AgCl(s).

AgNO3 + CaCl2 -> AgCl + Ca(NO3)2 is the result of the given reaction

One mole of AgNO3 interacts with one mole of CaCl2 to produce one mole of AgCl in this reaction.

Given that AgNO3 (v1) has a volume of= 100 ml

Volume of CaCl2(v2) = 90ml

molarity of AgNO3 (m1) = 0.400M

Molarity of CaCl2 (m2) = 0.250M

Moles of AgNO3 formed: v1 x m1/1L = 0.1 x 0.4/1 = 0.04

moles of CaCl2 formed: v2 x m2/1L = 0.09 x 0.25/1L = 0.0225

Since AgNO3 exceeds 0.0225 moles of AgCl, CaCl2 is the limiting reactant in this limiting reactant problem.

Hence the number of moles of AgCl formed = 0.0225

determine the value of kp for the following reaction: 4hcl(g)+o2(g)⇌2cl2(g)+2h2o(g)

Answers

The equilibrium constant at a temperature of 25°C is Kp = 28.18. This value can be expressed to three significant digits as Kp = 28.2.

What exactly is balance?

A state of balance between conflicting forces or influences is known as equilibrium. It is a principle that is applied in a variety of fields, including as physics, chemistry, and economics.

The following equation can be used to determine the equilibrium constant for the specified reaction:

Kp = [Cl₂]²[H₂O]² / [HCl]⁴[O₂]

The partial pressures of the gases can be used to determine Kp on the assumption that the gas is ideal.

Kp = (PCl₂)²(PH₂O)²/ (PHCl)⁴(PO₂)

Kp is easily calculable if the partial pressures of each gas are known. Finding the equilibrium constants at a given temperature is important because no pressures are provided in this scenario.

According to the information in the thermochemical table, Kp = 28.18 is the equilibrium constant at 25°C. 3 significant figures can be used to express this amount Kp = 28.2.
