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. 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 Surface reaction between A in the gas phase and absorbed B Surface reaction between absorbed A and absorbed B ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering If ΔG (free energy change) for a chemical reaction is very large and negative, then the reaction is Not feasible Just feasible Very much feasible Unpredictable as ΔG is no measure of feasibility of a reaction Not feasible Just feasible Very much feasible Unpredictable as ΔG is no measure of feasibility of a reaction ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering At a given temperature, K₁, K₂ and K3 are equilibrium constants for the following reactions 1, 2, 3 respectively. CH₄(g) + H₂O(g) ⇋ CO(g) + 3H₂(g), CO(g) + H₂O(g) ⇋ CO₂(g) + H₂(g) CH₄(g) + 2H₂O(g) ⇋ CO₂(g) + 4H₂(g) Then K₁, K₂ and K3 are related as: K3 = (K₁.K₂)2 K3 = K₁.K₂ K3(K₁+K₂)/2 K3 = (K₁.K₂)0.5 K3 = (K₁.K₂)2 K3 = K₁.K₂ K3(K₁+K₂)/2 K3 = (K₁.K₂)0.5 ANSWER DOWNLOAD EXAMIANS APP
