Chemical Reaction Engineering When the reaction is dominated by in-traparticle diffusion, the apparent order of reaction (nD) as measured is related to the true order (n) as ND = n + 1 ND = n/2 ND = (n + 1)/2 None of these ND = n + 1 ND = n/2 ND = (n + 1)/2 None of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In Langmuir treatment of adsorption, Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule Extent of adsorption is more than one complete monomolecular layer on the surface Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site All the adsorption does not take place by the same mechanism Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule Extent of adsorption is more than one complete monomolecular layer on the surface Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site All the adsorption does not take place by the same mechanism ANSWER DOWNLOAD EXAMIANS APP
