For a heterogeneous 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
(A) Surface Kc
/(1 + TS
) reaction between absorbed A and B in the gas phase
(B) Surface reaction between absorbed A and absorbed B
(C) Surface reaction between A in the gas phase and absorbed B
(D) Desorption of C
of A and B, the initial rate - rA0
is invariant with total pressure. The rate
controlling step is
(A) Surface Kc
/(1 + TS
) reaction between absorbed A and B in the gas phase
(B) Surface reaction between absorbed A and absorbed B
(C) Surface reaction between A in the gas phase and absorbed B
(D) Desorption of C
