According to the adsorption theory of catalysis the speed of the reaction increases becauseA. adsorption lowers the activetion energy of the reactionB. the concentration of reaction molecules at the active centres of the catalyst becomes high due to adsorptionC. in the process of adsorption, the activation energy of the molecules becomes largeD. adsorption produces heat which nincrease the speed of the reaction |
|
Answer» Correct Answer - A In surface catalysis or heterogeneous catalysis, the reaction becomes fast on account of lowering of activation energy. The old view point was that the increased concentration of the reactants on the surface influences the rate of reaction. |
