In the manufacture of ammonia by Haber's process,
`N_(2)(g) +3H_(2)(g) hArr 2NH_(3)(g)+92.3kJ`, 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:
A
For this reaction `Deltan` is negative & `DeltaH` is negative so it take forward by decrease in temperature.
