A constant-volume calorimeter was calibrated by carrying out a reaction known to release 0.704 kJ of heat in 0.600 L of solution in the calorimeter (q = -0.704 kJ), resulting in a temperature rise of 2.76 °C. In a subsequent experiment, 300.0 mL of 0.40 M HCI0, (aq) and 300.0 mL of 0.40 M NAOH(aq) were mixed in the same calorimeter and the temperature rose by 5.90 °C. What is the change in the internal energy of the reaction mixture as a result of the neutralization reaction? AU= kJ TOOLS x10
