MCQ
On the velocity in a reversible reaction, the correct explanation of the effect of catalyst is
  • ✓
    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

Correct option: A.
It provides a new reaction path of low activation energy
(a) 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.
