For 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, Delta_(c)H for the reaction will be (R = 8.314 J mol^(-1))

For complete combustion of ethanol, C_(2)H_(5)OH(l) + 3O_(2)(g) to 2C

1.	For 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, Delta_(c)H for the reaction will be (R = 8.314 J mol^(-1))
Answer» `-1350.50 kJ"MOL"^(-1)` `-1366.95 kJ"mol"^(-1)` `-1361.95 kJ"mol"^(-1)` `-1460.50 kJ"mol"^(-1)` SOLUTION :In a bomb CALORIMETER, VOLUM is constant .Heat RELEASED at constant volume = `DeltaU = -1364.47 kJ ` `R = 8.314 xx 10^(-3)kJK^(-1) "mol"^(-1)` `Deltan_(g) = 2 -3 =-1` `DeltaH = DeltaU + Deltan_(G) Rt` ` = -1364.47 + (-1) (8.314 xx 10^(-3))(298)` ` = -1366.95 kJ"mol"^(-1)`
