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?

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