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 All the adsorption does not take place by the same mechanism 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 Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule All the adsorption does not take place by the same mechanism 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 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering If n = overall order of a chemical reaction. a = initial concentration of reactant. t = time required to complete a definite fraction of the reaction. Then pick out the correct relationship. T ∝ 1/an - 1 T ∝ 1/an T ∝ 1/an + 1 T ∝ an T ∝ 1/an - 1 T ∝ 1/an T ∝ 1/an + 1 T ∝ an ANSWER DOWNLOAD EXAMIANS APP
