Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Collision frequency increases Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Value of threshold energy decreases Collision frequency increases Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Value of threshold energy decreases ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In Langmuir treatment of adsorption, 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 Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule ANSWER DOWNLOAD EXAMIANS APP
