For the complete combustion of ethanol, C_(2)H_(5)OH(l)+3O_(2)(g) to 2CO_(2)(g)+3H_(2)O(l) the amount of heat produced as measured in bomb calorimeter is 1364.47 kJ mol^(-1) at 25^(@)C. Assuming ideality, the enthalpy of combustion DeltaH_("comb") for the reaction will be (R=8.314 J K^(-1)mol^(-1))

Answer»

`-1366.95kJmol^(-1)`
`-1361.95kJmol^(-1)`
`-1460.50kJmol^(-1)`
`-1350.50kJmol^(-1)`

Solution :`DeltaU=-1364.47,Deltan_(G)=-1,R=(8.314)/(1000)`
USE `DeltaH=DeltaU+Deltan_(g)RT)`
