Q. The %yield of ammonia as a function of time in the reaction
$N_{2}\left(g\right) + 3H_{2}\left(g\right) {\rightleftharpoons} 2NH_{3}\left(g\right), ΔH < 0$
at $\left(P, T_{1}\right)$ is given below.
If this reaction is conducted at $\left(P, T_{2}\right)$, with $T_{2} > T_{1}$, the %yield of ammonia as a function of time isrepresented by -Chemistry Question Image

Solution:

Initially larger is the temperature greater is the yield but due to exothermic reaction as the time lapse yield become less.
