According to the adsorption theory of catalysis, the speed of reaction increases because
Options
- Aadsorption lowers the activation enegry of the reaction
- Bthe concentration of reactant molecules at the active centres of the catalyst becomes high due to adsorption
- Cin the process of adsorption, the activation energy of the molecules becomes large
- Dadsorption produces heat which increases the speed of the reaction
Correct answer
A. adsorption lowers the activation enegry of the reaction
Step-by-step solution
In heterogeneous catalysis, adsorption lowers the activation energy of the reaction.
