    +8 J/mol

    Explanation:

    The following were obtained from the question:

    Mole of the compound = 3 moles

    Heat Energy used = 24J

    Hreaction = ?

    The heat of reaction is the energy released or absorb during a chemical reaction. It is can obtained mathematically by the following equation:

    Hreaction = Heat energy/mole

    With the above equation, we can easily find the Hreaction for the question given as follow:

    Hreaction = Heat energy/mole

    Hreaction = 24J / 3mol

    Hreaction = 8 J/mol

    Since the compound used the energy, the Hreaction is + 8 J/mol
