Chemical equilibrium is a dynamic equilibrium because

A

the rate of forward reaction in nonzero

B

the rate of backward in nonzero

C

concentrations of reactants and products always keep changing

D

Both forward and backward reactions occur simultaneously at the rate which is nonzero.

Text Solution

Verified by Experts

The correct Answer is:
D

At equilibrium, individual molecules are continually reacting, even though the overall composition of the reaction mixture does not change because the rates of forward and backward reactions are equal.
