Now that you have an equation for the line of best fit of this first order reactant, use it to determine the rate constant (including units) for this reaction.
The y-intercept would be ln(Pch3nc)0

13.0 mol of N2 will be used up in the reaction, and there will be no N2 left over. Therefore, the answer to your question is that none of the N2 will be left over after the reaction is complete.

The balanced chemical equation for the reaction of nitrogen and hydrogen gas to form ammonia gas is:

N2 + 3H2 -> 2NH3

From this equation, we can see that one mole of N2 reacts with three moles of H2 to produce two moles of NH3.

So, if we have 13.0 mol of N2 and 9.0 mol of H2, the limiting reactant is N2 because it is in excess. This means that all of the H2 will react with the N2, and some of the N2 will be left over.

To calculate how much N2 is left over, we first need to determine how many moles of NH3 are produced. Since one mole of N2 reacts with three moles of H2 to produce two moles of NH3, we can use the mole ratio to calculate the number of moles of NH3 produced:

13.0 mol N2 x (2 mol NH3 / 1 mol N2) = 26.0 mol NH3

So, 26.0 mol of NH3 will be produced from the reaction of 13.0 mol of N2 and 9.0 mol of H2.

Next, we need to use the mole ratio again to determine how much N2 is left over. Since one mole of N2 reacts with two moles of NH3, we can use the mole ratio to calculate how many moles of N2 are needed to produce 26.0 mol of NH3:

26.0 mol NH3 x (1 mol N2 / 2 mol NH3) = 13.0 mol N2

This means that all 13.0 mol of N2 will be used up in the reaction, and there will be no N2 left over.

Therefore, the answer to your question is that none of the N2 will be left over after the reaction is complete.

A better nucleophile between Iodine (I) and Fluorine (F) is Iodine (I). This is because nucleophilicity generally increases as we move up and to the left in the periodic table

The nucleophilicity of a species is determined by its ability to donate an electron pair and form a new bond with an electrophile. Iodine is a better nucleophile because it has a larger atomic radius than Fluorine, which means that its valence electrons are further away from the positively charged nucleus. This results in a weaker electrostatic attraction between the nucleus and the valence electrons, making Iodine's valence electrons more readily available to donate and form a new bond with an electrophile.

For heat to transfer from a high temperature to a low temperature, the entropy of the entire system usually increases.

The second law of thermodynamics states that the total entropy of a closed system will always increase over time. In the case of heat transfer, the high-temperature system loses heat to the low-temperature system, and this results in an increase in the entropy of both systems.

The increase in entropy occurs because heat flows spontaneously from a high-temperature region to a low-temperature region.

As the heat flows, the disorder or randomness of the molecules in the low-temperature region increases, resulting in an overall increase in entropy. This increase in entropy is consistent with the second law of thermodynamics, which states that any process that occurs in a closed system will result in an increase in entropy.

The lower reactivity of 2,2-dimethyl-1-bromopropane in the Sn2 reaction compared to bromoethane can be attributed to steric hindrance. The two methyl groups on the carbon adjacent to the bromine in 2,2-dimethyl-1-bromopropane create a bulky structure that hinders the approach of the nucleophile during the Sn2 reaction.

This hindrance slows down the reaction and makes it less favorable compared to bromoethane, which has a simpler structure with no such hindrance.

Therefore, even though both are primary alkyl halides, the presence of the bulky methyl groups makes the Sn2 reaction of 2,2-dimethyl-1-bromopropane significantly lower than bromoethane.
The Sn2 reaction of 2,2-dimethyl-1-bromopropane is significantly lower than bromoethane because of the steric hindrance in the former compound.

Both are primary alkyl halides, but 2,2-dimethyl-1-bromopropane has two methyl groups attached to the carbon bearing the bromine atom, making it more sterically hindered.
