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

keff = (k+ kg)/2

1/keff = 1/k + 1/kg

keff = k + kg

keff = (kkg)1/2

keff = (k+ kg)/2

1/keff = 1/k + 1/kg

keff = k + kg
