In Haber's process, ammonia is manufactured according to the following reaction
`N_(2(g)) + 3H_(2(g)) hArr 2NH_(3(g)) , Delta H^(@) = -2.4 kJ`
The pressure inside the chamber is maintained at 200 atm and temperature at `500^(@)C`. Generally this reaction is carried out in presence of Fe catalyst.
The preparation of ammonia by Haber's process is an exothermic reaction. If the preparation follows the following temperature pressure relationship for its % yield. Then for temperature `T_(1), T_(2)` and `T_(3)`, the correct option is :

A

`T_(3) lt T_(2) lt T_(1)`

B

`T_(3) gt T_(2) gt T_(1)`

C

`T_(1) = T_(2) = T_(3)`

D

`T_(1) gt T_(2) lt T_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
The % yield will decrease with rise in temperature since it is exothermic.
