The reaction
2NaOH(aq) + H₂SO₄(aq) $\to$ Na₂SO₄(aq) + 2H₂O(l)
was studied in a coffee cup calorimeter. 100. mL portions of 1.00 M aqueous NaOH and H₂SO₄, each at 24.0°C, were mixed. The maximum temperature achieved was 30.6°C. Neglect the heat capacity of the cup and the thermometer, and assume that the solution of products has a density of exactly 1 g/mL and a specific heat capacity of 4.18 J/(g·K).
a. Calculate the heat of reaction, q, in J.
b. Calculate $\Delta$ H, the heat (enthalpy) of reaction, in kJ/mol of Na₂SO₄ produced.
