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.© BrainMass Inc. brainmass.com March 4, 2021, 8:34 pm ad1c9bdddf
The temperature change is
deltaT = 22.93 - 19.18 = 3.75 ...
The solution shows how to calculate the heat capacity of the calorimeter using the combustion of benzoic acid.
