A dilute solution of hydrochloric acid with a mass of 606.80 g and containing 0.30015 mol of HCl was exactly neutralized in a calorimeter by the sodium hydroxide in 612.93 g of a comparably dilute solution. The temperature increased from 16.222 to 19.624degree (C). The specific heat of the HCl solution was 4.031 J ·g-1 · °C-1; that of the NaOH solution was 4.046 J ·g-1 · °C-1. The heat capacity of the calorimeter was 77.99 J · °C-1.

a) Write the balance equation for the reaction ( include states)

b) What is the heat of neutralization per mole of HCl? Assume that the original solutions made independent contributions to the total heat capacity of the system following their mixing. ( in kJ/mol)
