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 1/keff = 1/k + 1/kg keff = (k+ kg)/2 keff = (kkg)1/2 keff = k + kg 1/keff = 1/k + 1/kg keff = (k+ kg)/2 ANSWER DOWNLOAD EXAMIANS APP
