there are 2 Questions in which they seem like they should have the same answer, but apparently they dont, which is confusing.
1. 2NH3 <--> N2(g) + 3H2(g) initially, NH3 is added to empty flask. how do rates of forward and reverse reactions change as system proceeds towards eqm?
answer: forward rate decreases and reverse rate increases.
2. 2HBr (g) <--> H2(g) + Br2 (g) initially, HBr is added to empty flask. how do rate of forward reaction and [HBr] change as system proceeds to eqm?
answer: forward rate increases and reverse rate increases.
why are the answers almost opposite? is it because of [HBr] in question2? it seems like the 2 questions are the same..
