Question

When a catalyst is added to a system, the: (A) value of equilibrium constant is decreased (B) the rate of forward reaction is increased and of backward reaction is decreased (C) equilibrium concentrations are unchanged (D) equilibrium concentrations are increased

Tardigrade Admin · Accepted Answer

A catalyst increase the rate of both forward and backward reactions equally and thus brings about the equilibrium state early but does not change the concentration at equilibrium i.e., equilibrium constant is unchanged.

Q. When a catalyst is added to a system, the:

value of equilibrium constant is decreased

the rate of forward reaction is increased and of backward reaction is decreased

equilibrium concentrations are unchanged

equilibrium concentrations are increased

A catalyst increase the rate of both forward and backward reactions equally and thus brings about the equilibrium state early but does not change the concentration at equilibrium i.e., equilibrium constant is unchanged.
