For the reaction `2A (g) + B(g) to C (g)`
`Delta U^(@) = 20` kcal/mole, `Delta S^(@) = 100` cal/kmole at 300 K. Hence `Delta G^(@)` in kcal is __________
`[R = 2 cal mol^(-1) K^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
`-1.2`
`2A(g)+B(g)toC(g)`
`DeltaH^(@)=DeltaU^(@)+Delta n_(g)RT=30+((-2)xx2xx300)/(1000)=28.8` K cal / mole
`DeltaG^(@)=DeltaH^(@)-T DeltaS^(@)=28.8-(300xx100)/(1000)=-1.2` kcal / mole
