In heterogenous catalysis of a gaseous reactants over solid catalyst
Reaction occurs when gases diffuse towards the surface of catalyst
Reaction starts when gases are about to desorb from the catalyst surface
Reaction occurs before adsorption of reactants
Reaction occurs on the surface of catalyst
The reactant gases adsorb on the surface of catalyst and on the surface itself reaction occurs.
If Pt is used as catalyst in the decomposition of H2O2, then it is an example of
