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
`DeltaG^(@)=-RT " ln" K. DeltaG^(@_ gt 0` means `Delta g^(@) ` is + ve. This can be so only if ln K is - ve , i.e., `K lt 1`.
