Question

What are factors that determine the path of a chemical reaction? Explain each factor.

Answer 1

Any idea, Xishem?

Answer 2

Hmm. I'm not exactly sure on the terminology here. I'm going to assume that "path of a chemical reaction" is essentially synonymous with "rate of a chemical reaction."

In which case there are 4 factors that determine the "path" of a chemical reaction:

1.) Temperature. The higher the temperature, the higher the average kinetic energy of the particles, the more collisions that will occur.

2.) Concentration of the reactants. The more concentrated reactant are, a larger percentage of the system they inhabit, causing it to be more likely for them to collide and react.

3.) Presence of catalyst or inhibitor. Catalysts lower the activation energy of the reaction. Inhibitors work in many different ways.

4.) Medium of reaction. Sometimes the medium of the reaction will change the rate of the reaction, whether it's liquid, gaseous, polar, nonpolar, etc..

That's the best I can do for you. I'm not even sure if that's what the question is asking, though. Does this sound reasonable?

Answer 3

I thought the same thing when the professor phrased the question this way. I was really lost on how to answer the question. Thank you Xishem!

Answer 4

Yep (: Good luck, and I hope that's the answer your professor was looking for.

Answer 5

I have one more question... What are five examples of calculating heat of formation from bond dissociation energy?

Answer 6

Five? :3

It's strange that you would be asked this. Most of the time, the question and various other information would have to be provided to you to be able to calculate the heat of formation from BDEs. It'd be strange if you were asked to conjure examples.

Answer 7

It's not specifically five but need to have at least five...

Answer 8

Still, it seems strange that you would be asked to just produce them. I guess you could look up various examples and write them down.

Other than that, you need to have some sort of reaction where all reactants and products are in the gas state, and you need to be given the BDE of each bond that's associated in those reactants and products.

Answer 9

I think it is more of a conceptual question...

Answer 10

I have no idea what your instructor is asking for then ): I'm sorry. Good luck.

Answer 11

Thank you for all your help! :)

Answer 12

Let me post a random question so I can give you another medal for good answer

Answer 13

go to the "What is the atomic mass of hydrogen?" question
