A quantity of 1.00 x 102 mL of 0.500 M HCl was mixed with 1.00 x 102 mL of 0.500 M NaOH in a constant pressure calorimeter of negligible heat capacity. The initial temperature of the HCl and NaOH solutions was same, 22.50°C, and the final temperature of the mixed solution was 25.86°C. Calculate the (a) heat of the reaction at constant pressure (qp) and (b) the change in enthalpy for the neutralization reaction (ΔHrxn) in kJ per mole of HCl. Assume that the densities and specific heat of the solutions are the same as for water (1.00 g/mL and 4.184 J/g °C, respectively). NaOH(aq) + HCl(aq) -> NaCl(aq) + H2O(l)
