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 reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C ANSWER DOWNLOAD EXAMIANS APP
