Question

For the manufacture of ammonia by the reaction
N₂ + 3H₂⇌2NH₃ + 2 kcal
the favourable conditions are
(a) Low temperature, low pressure and catalyst
(b) Low temperature, high pressure and catalyst
(c) High temperature, low pressure and catalyst
(d) High temperature, high pressure and catalyst

Answer 1

Answer:

c) high temperature,low pressure and catalyst

Answer 2

(b) Low temperature, high pressure and catalyst

Explanation:

The process of manufacturing of ammonia is an exothermic process. On increasing temperature, the reaction will try to move in backward direction to neutralize its effect given by Le chatelier principle. So the ideal condition for the process will be low temperature, high pressure and catalyst. Option B is the answer.
