Chemical and Ionic Equilibrium 1 Question 28
29. The $%$ yield of ammonia as a function of time in the reaction, $\mathrm{N}{2}(g)+3 \mathrm{H}{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g) ; \Delta H<0$
(2015 adv.)
at $\left(p, T_{1}\right)$ is given below.
If this reaction is conducted at $\left(p, T_{1}\right)$, with $T_{2}>T_{1}$ the $%$ yield by of ammonia as a function of time is represented by
(a)
(c)
(b)
Show Answer
Solution:
- Since, the reaction is exothermic, there will be less ammonia at equilibrium and higher temperature. However, rate of reaction increases with rise in temperature, $\mathrm{NH}_{3}$ will be formed at faster rate in the initial stage when the temperature is high.
