Question

According to adsorption theory of catalysis, the rate of reaction increases with the use of a catalyst because:

• A. the heat liberated during adsorption increases the rate of reaction
• B. the kinetic energy of reactants increases which increases the rate of reaction
• C. the activation energy of reaction increases which increases the rate of reaction
• D. the concentration of reactants at the active centres becomes high due to adsorption resulting in increase in the rate of reaction.

Answer 1

The correct option is D the concentration of reactants at the active centres becomes high due to adsorption resulting in increase in the rate of reaction.

According to adsorption theory of catalysis the rate of reaction increases with the concentration of reactants will come and stick at the surface catalyst (usually metals) at the active centers becomes high due to adsorption resulting in increase in the rate of reaction.

Ans :- Option D.
