Re: Catalyst question
From what I've read I'm pretty sure that catalysts should be included in the rate law expression because they affect the reaction rate, BUT catalysts are not included in the equilibrium constant expression because they do not affect the overall equilibrium.

Re: Basic Mechanisms
The arrows show the movement of electrons so the source of electrons is the nucleophile and the arrow shows that they move to the electrophile because they are attracted to its more positive charge

Re: Bronsted vs Lewis Acid Definition
Are there going to be conceptual questions on the final like explaining the difference between the two?

Re: Lewis Structure of Ionic vs. Covalent
Is it because we're supposed to know that ammonium is an ion so its bonds are always ionic?

Re: Quiz Preparation #5 [ENDORSED]
I think kinetic energy is 0 because this is the point where the electron would just begin to have any sort of kinetic energy.
