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-TDeltaS`
`=49.4-(300xx336xx10^(-3))`
`=-51.4kJ`
Since, the free energy change is negative, the given reaction is spontaneous.
