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 Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site Extent of adsorption is more than one complete monomolecular layer on the surface 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 Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site Extent of adsorption is more than one complete monomolecular layer on the surface All the adsorption does not take place by the same mechanism ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is 2 3 0 1 2 3 0 1 ANSWER DOWNLOAD EXAMIANS APP
