### Re: Spontaneity question

To keep it simple, negative delta G values mean it is spontaneous. You obtain delta G by taking into consideration the enthalpy and entropy values.

What does sublimize mean again?

### Re: Functional Groups

Being able to identify the functional groups would have been enough to suffice. Hope that helped!

Yeah I wouldn't assume that it is always reversible.

What difference does it make when the reactants sit on the surface versus when they go inside?

Deriving rate laws will allow you to combine different formulas you have to come up with unique answers for problems you may come across.

### Re: Bond enthalpies

Are these enthalpies Okay to use because I think Dr. Lavelle said that they were the most innacurate

Okay I see this but how will this affect the different types of formulas we are going to have to use?
