Question

Regarding the rate of a reversible reaction, the correct explanation of the effect

of catalyst is

• A. It provides a new reaction path of low activation energy
• B. It increases the kinetic energy of reacting molecules
• C. It displaces the equilibrium state on right side
• D. It decreases the velocity of backward reaction

Answer 1

The correct option is A

It provides a new reaction path of low activation energy

Effect of catalyst is that it attains equilibrium quickly by providing a new

reaction path of low activation energy. It does not alter the state of

equilibrium.
