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 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For a heterogenous catalytic reaction, A + B → C, with equimole feed of A and B, the initial rate - rA0 is invariant with total pressure. The rate controlling step is Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C Surface reaction between absorbed A and absorbed B Surface reaction between A in the gas phase and absorbed B Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C Surface reaction between absorbed A and absorbed B Surface reaction between A in the gas phase and absorbed B ANSWER DOWNLOAD EXAMIANS APP
