In a reaction A(2)(g)+4B(2)(g) hArr 2AB(...

In a reaction `A_(2)(g)+4B_(2)(g) hArr 2AB_(4)(g), DeltaH lt 0`. The formation of `AB_(4)` is not favoured by

A

low temperature and high pressure

B

high temperature nad low pressure

C

low temperature and low pressrue

D

high temperature and high pressrue

Text Solution

Verified by Experts

The correct Answer is:
A
Since , the reaction is exothermic , the formation of `AB_(4)` is favoured by low temperature .
As the forward reaction is accompanied by decrease in the number of moles, so if is favoured by high pressure.
