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