    Benzoic acid (C6H5COOH) is sometimes used as a standard to determine the heat capacity of a bomb calorimeter.

    When 1.44 g C6H5COOH is burned in a calorimeter that is being calibrated, the temperature rises from 19.18 degrees Celsius to 22.93 degrees Celsius. What is the heat capacity of the calorimeter? The heat of combustion of benzoic acid is -26.42 kJ/g.

    The temperature change is
    deltaT = 22.93 - 19.18 = 3.75 ºC

    The heat involved by the 1.44 g benzoic acid is
    Q = mq = 1.44 g * (26.42 k/g) =38.0448 kJ

    therefore, the heat capacity of the calorimeter is
    C = Q / deltaT = 38.0448 kJ / 3.75 ºC = 10.15 kJ/ºC.
