OK I clicked a bunch of similar discussions, but it still makes no sense, I barely know what a catalyst is, besides the fact that they do affect the rate of reaction but not the equilibrium expression or pressure, which just got me hella fudged up. And i don't want any over complicated explanations lmoa, but any help would be greatly appreciated. ---Also, when writing a reaction, I get really confused on how the products are set up, after that I can't easily calculate PH and such, and I do know it involves how strong or weak the acids and bases are, and if it lends protons or not, but I don't really understand how any of this works together to tell you how the products are set up Ex; HOCl + H20 <--> H30+ + OCL- obviously this is correct but I don't understand how they got H30, and not OH, and H2OCL, any descriptions on this would help. I hope im not restricting any guidelines cause this isnt really a problem in my hw, its just helpful in many parts to it. Sorry if my questions sound stupid, I honestly don't know sometimes how I manage AP Chemistry, But im always looking for more ways to succeed!!!
