Chemical Reaction Engineering
A first order gaseous phase reaction is catalysed by a non-porous solid. The kinetic rate constant and the external mass transfer co-efficients are k and kg respectively. The effective rate constant (keff) is given by

keff = (kkg)1/2

1/keff = 1/k + 1/kg

keff = k + kg

keff = (k+ kg)/2

keff = (kkg)1/2

1/keff = 1/k + 1/kg

keff = k + kg

keff = (k+ kg)/2

Chemical Reaction Engineering
For a heterogeneous catalytic reaction

The catalyst does not form an intermediate complex with the reactant

A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important

The surface of the catalyst does not play an important role during reaction

Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction
