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 A in the gas phase and absorbed B Surface reaction between absorbed A and B in the gas phase Absorption of A Surface reaction between absorbed A and absorbed B Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and B in the gas phase Absorption of A ANSWER DOWNLOAD EXAMIANS APP

Chemical Reaction Engineering For identical flow rate, feed composition and for elementary first order reactions, 'N' equal sized mixed reactors in series with a total volume 'V' gives the same conversion as a single plug flow reactor of volume 'V' for constant density systems. This is true, when the value of 'N' is ∞ 1 >1 ≥1 ∞ 1 >1 ≥1 ANSWER DOWNLOAD EXAMIANS APP
