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, high pressure

B

`High temperature, low pressure

C

Low temperature, low pressure

D

High temperature, high pressure

Text Solution

Verified by Experts

The correct Answer is:
A
According to Le-Chatelier's principle, exothermic reaction is forwarded by low temperature, in forward direction number of moles is less, hence pressure is high.
