Published on: August 14, 2026

In a reversible chemical reaction, the rate of forward reaction decreases and that of backward reaction increases with the passage of time ; at equilibrium the rate of forward and backward reactions become same. Let us consider the formation of SO 3 (g) in the following reversible reaction: 2SO 2 (g) + O 2 (g) 2SO 3 (g) Following graphs are plotted for this reactions

(i) In the above graph, A B & C respectively are
