C: None of them. Catalysts reduce the energy barrier between reagents and products, by helping to form reactive intermediates that subsequently break down into the finished products. This means that there is less of an energy barrier to overcome, which means that the reaction can occur much faster for the same energy input. Catalysts do not have any impact on the position of an equilibrium, only on the reaction speed.

i hated chemistry, and i might not hated it if a teacher named tatiana myagkova (might be with or without an "a", since she is russian), who can't and DOES NOT KNOW HOW TO TEACH DID NOT TEACH ME (you can find that freak if you google her). geez, i might not have hated chemistry if i didn't have that idiot. sigh, and she came from CAL TECH too. well, what i learned from BEING ASSIGNED CHAPTERS FOR SELF-READING BY THAT FREAK is that a catalyst lowers the activation energy of a reaction. so choice #1. i hope that you enjoy chemistry, and that you have teacher THAT CAN TEACH WELL. =D
