Sorry you've not had any responses about this. Are you sure you’ve posted in the right place? Posting in the specific Study Help forum should help get responses.

I'm going to quote in Puddles the Monkey now so she can move your thread to the right place if it's needed. :yy:

Let's get this thread started again..! I have a question, anyone want to explain to me what the hell a Ziegler Natta catalyst is? The pre-lease doesn't make it very clear in my opinion

Question 1: what is the difference between heterogeneous and homogeneous catalysts?
So do we all agree that the heterogeneous catalyst is an a different physical state to the reactants whilst the homogeneous catalyst is in the same physical state to the reactants?
Is that the only difference/what are others?

heterogeneous catalysts are used alot more in industry and tend to be more stable and degrade much slower than homogeneous catalysts.

homogeneous catalyst is usually in gas and liquid state while a heterogeneous catalyst surface tends to be in a solid state
