In the complete combustion of butanol C(...

In the complete combustion of butanol `C_(4)H_(9)OH(l)`, if `Delta H` is enthalpy of combustion and `Delta E` is the heat of combustion at constant volume, then

`DeltaH lt DeltaE`

`DeltaH = DeltaE`

`DeltaH gt DeltaE`

`DeltaH, DeltaE` relation cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:

In the complete combustion of butanol `DeltaHgtDeltaE`.
