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 - ΔHR ΔHA + ΔHR E + ΔHA E E + ΔHA - ΔHR ΔHA + ΔHR E + ΔHA E ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be Higher in CSTR Data insufficient; can't be predicted Higher in P.F. reactor Same in both the reactors Higher in CSTR Data insufficient; can't be predicted Higher in P.F. reactor Same in both the reactors ANSWER DOWNLOAD EXAMIANS APP
