The % yield of ammonia as a function of time in the reaction
$N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g), Δ H < 0$ at $(P, T_{1})$ is given below.

If this reaction is conducted at $(P, T_{2})$ with $T_{2} > T_{1}$ , the % yield of ammonia as a function of time is represented by:

Initially on increasing temperature rate of reaction will increase, so $%$ yield will also increase with time. But at equilibrium $%$ yield at high temperature $(T_{2})$ would be less than at $T_{1}$ as reaction is exothermic so the graph is
