For the reaction,
`X_(2)O_(4)(l)rarr2XO_(2)(g),DeltaE=2.1Kcal` ,
`DeltaS=20cal//K` at `300K` . Hence `DeltaG` is

A

`2.7 kcal`

B

`-2.7 kcal`

C

`9.3 kcal`

D

`-9.3 kcal`

Text Solution

Verified by Experts

`DeltaH = DeltaU +Deltan_(g)RT`
`= 2.1 xx2xx 0.02 xx 300 = 3.3 kcal`
`DeltaG = DeltaH - T DeltaS`
`=3.3 xx -300 xx (0.02) =- 2.7 kcal`
