In the manufacture of ammonia by Haber's process, `N_(2(g))+ 3H_(2(g))Leftrightarrow 2NH_(3(g))+ "92.3 kJ"`, which of the following conditions is unfavourable?

A

Increasing the temperature

B

Increasing the pressure

C

Reducing the temperature

D

Removing ammonia as it is formed

Text Solution

Verified by Experts

The correct Answer is:
C
`N_(2) +3H_(2) (g) to 2NH_(3)+92.3kJ`
The reaction is exothermic `(triangleH=-ve)`. Therefore an increase of temperature, obviously disfavours the reaction.
