From the following data at constant volume for combustion of benzene, calculate the heat of this reaction at constant pressure condition.
`C_(6)H_(6(1))+71//2O_(2(g))rarr 6CO_(2(g))+13H_(2)O_((l))`

Text Solution

Verified by Experts

`DeltaE_(25^(@)C)=-781.1 kcal`
`DeltaH=DeltaE+DeltangRT`
`DeltaE=-781.1K.cal`
`Deltan_(g)=6-71//2=-1.5`
`(-1.5)xx1.987xx298`
`DeltaH=(-781.1+)/(1000)`
`=-781.1-0.888`
`therefore DeltaH=-782k.cal`
