The standard Gibbs free energy change `(DeltaG^0 )`25°C for the dissocitation of `N_(2)O_(4(g)) "to"NO_(2(g)` (given equilibrium constant = 0.15, R = 8.314 `JK^(-1)mol^(-1)`

A

1.1 kJ

B

4.7 kJ

C

8.1 kJ

D

38.2 kJ

Text Solution

Verified by Experts

The correct Answer is:
B

`Delta G^@ =-RT log K_(SP)`
`=-2.303 xx 8.314 xx 298 log (0.15) = + 4701 J `
