Question

In which of the following conditions do you think the rates of both forward and backward reactions are the same?

(a) unstable equilibrium

(b) not in an equilibrium

(c) the beginning of a reaction

(d) equilibrium

This question was posed to me in final exam.

The origin of the question is Equilibrium in Chemical Processes topic in section Equilibrium of Chemistry – Class 11

Answer 1

Right choice is (d) equilibrium

The best explanation: In a chemical reaction a state comes when both the forward and reverse reactions occur at the same rate and this state is known as equilibrium. At the beginning of the reaction, the rate of the Forward reaction is higher than the rate of backward reaction.
