For a given chemical reaction A to B at ...

For a given chemical reaction `A to B` at 300 K the free energy change is `-49.4 kJ mol ^(-1)` and the enthalpy of reaction is `51.4 kJ mol ^(-1).` The entropy change of the reaction is____________ `JK ^(-1) mol ^(-1).`

Text Solution

Verified by Experts

The correct Answer is:
336
`DeltaG = -49.4 kJ //mol`
`DeltaH = 51.4kJ//mol`
`DeltaG = DeltaH - T DeltaS`
`-49400 = 51400 - 300 DeltaS`
`DeltaS = ( + 100800)/(300) = 336 JK^(-1) mol^(-1)`.
