Question

87. For the following exothermic reaction N, (8)+3H2(g) = 2NH,(g). maximum yield of NH, is obtained at (a) Low temperature and low pressure (b) High temperature and high pressure (c) Low temperauture and high pressure (d) High temperature and low pressure ​

Answer 1

Answer:

Sorry this is textbook question

Answer 2

Answer:

correct opinion is d high temperature and low pressure

Explanation:

Correct option is

D

High pressure and low temperature

The manufacture of ammonia by Haber's process is an exothermic reaction. According to Le Chatelier's principle maximum yield of an exothermic reaction can be obtained at low temperatures. There are 4 molecules on reactant side and 2 on product side. According to Le Chatelier's principle if you increase the pressure the system will respond by favouring the reaction which produces fewer molecules. So the maximum yield of ammonia will be obtained at high pressure and low temperature
