Of the following reactions
(i) `ArArrB, DeltaG^(@)=250kjmol^(-1)`
(ii)`DrArrE, DeltaG^(2)= -100kjmol^(-1)`
(iii) `frArrG, Delta^(@)=-150kjmol^(-1)`
(iv) `MrArr N, DeltaG^(@)=150kjmol^(-1)`
reaction with the largest equilibrium constant is

A

I

B

II

C

III

D

IV

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaG^(@)=-2.303RT log_(10)K`
`logK=-(Delta G^(@))/(2.303RT)`
So lower value of `Delta G^(@)` higher will be log K
`FhArr G,DeltaG^(@)=-150kjmol^(-1)` (lowest)
