At `60^(@)C`, dinitrogen tetroxide is 50 per cent dissociated. Calculate the standard free energy change at this temperature and at one atmosphere.

A

`-863.8" Jmol"^(-1)`

B

`-963.8" Jmol"^(-1)`

C

`-973.8" Jmol"^(-1)`

D

`-789.7" Jmol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`{:(N_(2)O_(4),hArr,2NO_(2)),(1,,0),(1-0.5,,2xx0.5):}`
Total Moles `=1.5, DeltaG^(@)=-2.303 RT log K_(p)`
