Question

The % yield of ammonia as a function of time in the reaction $\mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) ightleftharpoons 2 \mathrm{NH}_{3}(\mathrm{~g}), \Delta \mathrm{H} < 0$ at $\left(\mathrm{P}, \mathrm{T}_{1}ight)$ is given below

If this reaction is conducted at $\left(\mathrm{P}, \mathrm{T}_{2}ight)$, with $\mathrm{T}_{2}>\mathrm{T}_{1}$, the \%yield of ammonia as a function of time is represented by

Aicharya · Accepted Answer

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