### Heterogenous vs homogenous

What determines if a heterogenous or homogenous catalyst should be used? What determines which is more effective?

I'm not sure if this answers your question, but one advantage of using heterogenous catalysts is that you can easily recover the catalyst for reuse whereas homogenous catalysts mix with the reaction so you can't really recover it

Typical reaction examples with a heterogeneous catalyst involve a solid catalyst with the reactants as either liquids or gases. Typically everything will be present as a gas if there is a homogeneous catalyst.
