The argument corresponding to the fact that catalysis step which occurs over a surface, leaves the energy of the products desorption and this step takes place with very little energy change is to be stated. Concept introduction: The process of increasing the rate of the reaction with the help of a catalyst is known as catalysis. The two types of catalysis are homogeneous catalysis and heterogeneous catalysis.
