allthebest Posted June 18, 2016 Report Share Posted June 18, 2016 I don't quite get how to make a rate equation/expression by seeing the mechanisms/ steps The overall reaction is given, and the step 1 and step 2 with slow and fast are given. I know that the rate expression should be made from the slow step (rate-determining step). But sometimes the reactants in the rate-determining step is not the same with the reactants in the overall reaction. Also, I'm quite confused with the order. Should I just follow like if the rate-determining step is P+Q --> X, then rate= [P][Q] because there is 1 P and 1 Q even though the overall reaction is 2P + Q --> R + S?? Please help me clarify... If you don't get what I'm saying, can you just please leave explanation of how to find the rate expression by seeing the overall equation and steps given? Thanks a lot in advance.
