Question

Catalyst increases the rate of reaction by
(a) decreasing threshold energy
(b) decreasing activation energy
(c) increasing activation energy
(d) decreasing equilibrium constant

Answer 1

Answer:

(c) increasing activation energy

Explanation:

Answer 2

(b) decreasing activation energy

Explanation:

The function of a catalyst is to lower the activation energy so that a greater proportion of the particles have enough energy to react. A catalyst can lower the activation energy for a reaction by reacting with the reactants to form an intermediate that requires lower energy to form the product.

Option B is the answer
