Question

The % yield of ammonia as a function of time in the reaction : N₂(g) 4 3H₂(g)  2NH₃(g), ∆ H < 0 at (P₁T₁) is given below.   

If this reaction is conducted at (P, T₂), with T₂ > T₁, the % yield of ammonia as a function of time is represented by

Answer 1

The correct answer is (B)

Initially on increasing temperature rate of reaction will increase, so % yield will also increase with time. But at equilibrium % yield at high temperature (T₂) would be less than at T₁ as reaction is exothermic so the graph is
