How many types of catalysis are there? Give the names.

(N/A) Catalysis is broadly classified into two main types based on the physical state of the reactants and the catalyst:
$1$. $Homogeneous \ catalysis$: In this type,the reactants and the catalyst are in the same phase (e.g.,all in liquid or all in gas phase).
$2$. $Heterogeneous \ catalysis$: In this type,the reactants and the catalyst are in different phases (e.g.,solid catalyst with gaseous or liquid reactants).
