HomeEngineeringA 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 8033. A first order gaseous phase reaction is catalysed by a non-porous solid.
