If `DeltaG^(@)` for the reaction given below is `1.7 kJ`, the equilibrium constant of the reaction,
`2HI_((g))hArrH_(2(g))+I_(2(g))` at `25^(@)C` is :

A

`24.0`

B

`3.9`

C

`2.0`

D

`0.5`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta G^(@) = - 2.303xx8.314xx10^(-3)xx298 log K_(p)`
`1.7 = - 2.303xx8.314xx10^(-3)xx298xxlog K_(p)`
`K_(p) = 0.5`
