1. The rate of the heterogenous catalytic reaction A(g) + B(g) C(g) is given by -rA = k.KA.pA.PB/(1 + KA.PA + Kc.pc), where KA and Kc are the adsorption equilibrium constants. The rate controlling step for this reaction is
(A): absorption of A.
(B): surface reaction between A in the gas phase and absorbed B.
(C): surface reaction between absorbed A and absorbed B.
(D): surface reaction between absorbed A and B in the gas phase.
