Enthalpy and entropy changes of reaction...

Enthalpy and entropy changes of reaction are `40.63 kJ mol^(-1)` and `108.8 J K^(-1) mol^(-1)`, respectively. Predict the feasibility of the reaction at `27^(@)C`.

Text Solution

Verified by Experts

`DeltaH=40.63KJmol^(-1)=40630Jmol^(-1)`
`DeltaS=108.8JK^(-1)mol^(-1)`
`T=27^(@)C=27+273=300K`
`DeltaG=DeltaH-TDeltaS`
`=40630Jmol^(-1)-300Kxx108.8JK^(-1)mol^(-1)`
`=7990Jmol^(-1)`
Since `DeltaG` comes out to be positure, the reaction is not feasible in the forward direction
