For the reaction :- N(2)O(4(g))hArr2NO(...

For the reaction :-
`N_(2)O_(4(g))hArr2NO_(2(g))`
`DeltaU2.0Kcal,DeltaS=50CalK^(-1)at300K` calculate `DeltaG`?

A

`+12.4K Cal`

B

`-12.4K Cal`

C

`-6.4K Cal`

D

`+6.4K Cal`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaH=2(1xx2xx300)/(1000)=2.6K Cal`
` DeltaG=DeltaH-TDeltaS`
`2.6-(300xx50)/(1000)=-12.4 K Cal`.
