Chemical Reaction Engineering 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 isA. absorption of A. Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B Absorption of A Surface reaction between absorbed A and B in the gas phase Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B Absorption of A Surface reaction between absorbed A and B in the gas phase ANSWER DOWNLOAD EXAMIANS APP
