A chemical reaction is in equilibrium when

A

formation of product is minimum

B

reactants are completely transformed into products

C

rates of forard and backward reactions are equal

D

equal amounts of reactants and products are present.

Text Solution

Verified by Experts

The correct Answer is:
C
A chemical reaction is in a state of equilibrium when the concentrations of the reactants and products do not change with time. This state is achieved when the rate of the forward reaction is equal to the rate of the backward reaction.
