The value of Delta H for the reaction X(...

The value of `Delta H` for the reaction `X_(2)(g) +4Y_(2)9g) hArr 2XY _(4)(g)` is less than zero. Formation of `XY_(4)(g)` will be favoured at `:`

A

low pressure and low temperature

B

high temperature and low pressure

C

high pressure and low temperature

D

high temperature and high pressure

Text Solution

Verified by Experts

The correct Answer is:
C
`X_2(g)+4Y_2hArr2XY_4(g)`, where `DeltaHlt0` and `Deltanlt0[Deltan=n_p-n_R]`
`therefore` The forward reaction is favoured at high pressure and low temperature.(According to Le -chatelier's principle).
