The solutions, all originally at 20°C, are combined in a calorimeter. The temperature of the reaction mixture is monitored, as show in the graph below. The magnitude of the molar enthalpy change calculated from the results of a second experiment is the same as the result calculated from the first experiment. Explain this result.
