In the manufacture of ammonia by the Haber's process, \(\mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g)+92.3 \mathrm{~kJ}\), which of the following conditions is unfavourable?
- A Reducing the temperature
- B Removing ammonia as it is formed
- C Increasing the temperature
- D Increasing the pressure
Answer & Solution
Correct Answer
(C) Increasing the temperature
Step-by-step Solution
Detailed explanation
For the following reaction, \(\mathrm{N}_{2}+3 \mathrm{H}_{2} \rightleftharpoons 2 \mathrm{NH}_{3}+923 \mathrm{~kJ}\) (i) Reducing temperature is favourable as it is an exothermic process and shift equilibrium towards right. (ii) Also on removing \(\mathrm{NH}_{3}\) equilibrium…
