When 200.0 mL of 0.862 M HCI is mixed with 200.0 mL of 0.431 M Ba(OH)2 in a coffee cup calorimeter, the temperature of the solution increases from 21.35°C to 27.05°C. Given the specific heat of solution of 4.18 Jg °C- and assuming the density of each solution to be 1.00 g/mL, what is the heat of reaction in kJ per mole of HCI? The neutralization reaction is: 2 HCI(aq) + Ba(OH)2(aq) → BaCl2(aq) + 2 H20(1)
