Calculate the free eneryg change at 298 K for the reaction ,
`Br_(2)(l)+Cl_(2)(g) to BrCl(g)`. For the reaction `DeltaH^(@)=29.3 kJ`&

Text Solution

Verified by Experts

The correct Answer is:
`-1721.8 J`
`DeltaS= 2 xx 239.7 - [152.3 +223]`
`= 104.1 J"mol"^(-1)K^(-1)`
`DeltaG = 29300- [298 xx104.1]`
`=- 1721. 8J`
