For the reaction `H_(2)(g) + I_(2) (g) hArr 2HI (g),` the standard free energy is `DeltaG^(Theta) gt 0.` the equilibrium constant (k) would be.

A

K=0

B

`K gt 1`

C

K=1

D

`K lt 1`

Text Solution

Verified by Experts

The correct Answer is:
D
`triangleG^(oplus)` and K are related as `triangleG^(oplus)=-RT ln K_(c)" when "G^(e) gt 0 " means "triangleG^(@)` is positive. This can be so only if `ln K_(c)` is negative i.e, `K_(c) lt 1.`
