Answer to Question #300758 in General Chemistry for angel

Question

The Haber process for the synthesis of ammonia from nitrogen and hydrogen gases in an exothermic process.

N2(g) + 3H2(g) ⇌ 2 NH3 (g) ΔHrxn= -92.4 kJ

How will the following conditions affect the equilibrium of the system?

a) adding more N2 =

b) removing 3H2 =

c) removing NH3 =

d) increasing the pressure in the reaction vessel =

e) decreasing the temperature of the system =

Answer 1

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.

Hence, increasing the temperature becomes unfavourable condition for manufacturing ammonia.
