3.00 g of glucose was placed on the sample holder in a bomb calorimeter. The initial temperature inside the calorimeter was 24.90 °C. After the ignition of the sample, the temperature was monitored. The maximum temperature was 29.20 °C. 1. Using the data in Table 18.1, determine AHrxn for the combustion of glucose (eq. 1). 2. Determine the calorimeter constant.
