For the reaction, SOCI(2) +H(2)O rarr ...

For the reaction,
`SOCI_(2) +H_(2)O rarr SO_(2)+2HCI`
the enthalpy of reaction is `40.0 kJ` and the entropy of reaction is `336 J K^(-1)`. Calculate `DeltaG` at `300K` and predict the neture of the reaction.

Text Solution

Verified by Experts

`DeltaG = DeltaH - T DeltaS`
`= 40.0 - (300 xx 336 xx 10^(-3)) =- 60.8 kJ`
Since the free enegry change is negative , the given reaction is spontaneous.
