Chemical Reaction Engineering The rate expression for a heterogenous catalytic reaction is given by, - rA = K.KA PA(1 + KA.PA + Kr.PR), where K is surface reaction rate constant and KA and KR are absorption equilibrium constants of A and R respectively. If KR PR >> (1 + KA PA), the apparent activation energy EA is equal to (given E is the activation energy for the reaction and ΔHR and ΔHA are the activation energies of adsorption of R and A) E + ΔHA ΔHA + ΔHR E E + ΔHA - ΔHR E + ΔHA ΔHA + ΔHR E E + ΔHA - ΔHR ANSWER DOWNLOAD EXAMIANS APP
