Question

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

• A. The heat liberated during adsorption increases the rate of reactions
• B. The kinetic energy of reactants increases which increases the rate of reaction
• C. The activations energy of reactions increases which increases the rate of reactions
• D. The concentrations of reactants at the active centres increases in the rate of reactions

Answer 1

Answer: (D)

The concentrations of reactants at the active centres increases in the rate of reactions

Answer 2

Due to adsorption the concentrations of reactants increases at active centres due to which rate of reactions increases
