Chemical Reaction Engineering If the time required to change the concentration of reactant to half its original value is independent of the initial concentration, the order of reaction is Three Zero Two One Three Zero Two One ANSWER DOWNLOAD EXAMIANS APP
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 E + ΔHA ΔHA + ΔHR E E + ΔHA - ΔHR E + ΔHA ΔHA + ΔHR E ANSWER DOWNLOAD EXAMIANS APP
