Catalysts

Postby Isabel Chu 2B » Tue Feb 23, 2016 1:44 pm

What exactly does it mean when a catalysts provides an alternative reaction pathway? I know the catalyst is not used up in the reaction, but how is it possible to have a completely different pathway?

When the book says that the catalyst has a completely different reaction pathway, I think that the "new path" entails lowering the activation energy, therefore being different from the original. I wouldn't say that it is completely different, and rather is very similar besides certain typical differences.

You are correct in that it will not always necessarily be a completely different pathway, but the activation energy will be lower. This is an example in which the pathway is different as there is an intermediate when the catalyst is present Image
