Catalysts on Final
Do you think we will be tested on our knowledge of catalysts on the final? If so, what are potential questions that could show up?

Re: Catalysts on Final
Maybe we would have to identify which substance is a catalyst, given steps of a reaction. Or perhaps conceptual questions about the effect of a catalyst?

Re: Catalysts on Final
if there is a question with a catalyst, I think it would be to identify what species is the catalyst in a reaction mechanism

Re: Catalysts on Final
probably when given some sort of mechanism you would need to be able to tell the difference between a catalyst and an intermediate. So the catalyst is not created but the intermediate is created and then is then used.

Re: Catalysts on Final
can someone explain how you know something is a catalyst? im confused on that.

Re: Catalysts on Final
I would imagine there wouldn't be an incredibly difficult question on catalysts, especially one requiring math, since we only went over catalysts very briefly in class.
Re: Catalysts on Final
Yeah, we haven't gone over how catalyst's act on the system mathematically, unless the problem tells us specifically that the catalyst lowers the Ea by x amount.

Re: Catalysts on Final
We would probably have to know some of the basics of a catalyst, and how to identify if there is one. In an energy graph, you would see the peak of the graph, or activation energy, lower if there is a catalyst. The catalyst increases the rates of both the forward and reverse reactions. But catalysts don't change the DeltaH of the reaction at all.
