Question

The enthalpy of combustion of benzoic acid (C6H5COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be – 3226.7 kJ/mol. (a) When 0.4654 g of a-D-glucose (C6H12O6) was oxidized the temperature rose from 21.22 °C to 22.28 °C. Calculate the enthalpy of combustion of glucose and the value of DUrxn for the combustion. (Hint: Be sure to write a balanced equation for each reaction first and assume the product H2O is a liquid).
