The change in internal energy for the combustion of 1.0 mol of octane at a pressure of 1.0 atm is 5084.3kJ. if the change is enthalpy is 5074.1kJ, how much work is done during the combustion?

  • chemistry -

    Internal energy = heat + work
    Work = Internal energy - heat

    heat = -5074.1kJ (combustion is always exothermic, so negative)

    work = -5084.3 kJ - (-5074.1) kJ =

  • chemistry -

    -10.2
