Question

For a reaction
`A(g)+3B(g)to2C(g)` , `DeltaH^(@)=-24kJ`
The value of `DeltaG^(@)` is `-9 kJ`. The standard entropy change of reaction is
A. `5 JK^(-1)`
B. `50 JK^(-1)`
C. `500 JK^(-1)`
D. `0.5 JK^(-1)`

Answer 1

Correct Answer - B
Apply `DeltaS^(@)=(DeltaH^(@)-DeltaG^(@))/(T)` Here, `T=298 K`
(Standard temperature)
