Question

Q-What are the conditions under which hydrogen and nitrogen combine to form ammonia?
a. Direct sunlight, normal atmospheric pressure
b. 450-500°C, 200-900 atmosphere pressure
Ć 1000°C, normal atmospheric pressure
d. Passing electric current through the mixture​

Answer 1

Answer:

N2(g)+3H2(g)↽−−⇀2NH3(g)(1)

With  ΔH=−92.4kJ/mol .

Explanation:

The Haber Process is used in the manufacturing of ammonia from nitrogen and hydrogen, and then goes on to explain the reasons for the conditions used in the process. The process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic.
