Question

When a catalyst is used in an equilibrium process:

• A. it increases the rate of forward reaction
• B. it decreases the rate of backward reaction
• C. it decreases activation energy of forward process and decreases activation energy of backward process
• D. it fastens the attainment of equilibrium by lowering activation energy

Answer 1

The correct option is D it fastens the attainment of equilibrium by lowering activation energy

Effect of catalyst in a chemical reaction:-

[1] Catalysts are compounds that accelerate the rate of a reaction.

[2] Catalysts accelerate reactions by reducing the energy of the rate-limiting transition state.

[3] Catalysts do not affect the equilibrium state of a reaction.

So the correct option is [D].
