When 5.022 g of sodium hydrogen carbonate NAHCO2(s) reacts completely with 80.00 mL of acetic acid CH3COOH(aq), the temperature increases from 18.6°C to 28.4°C. CH3COOH(aq)NaHCO2 (s) → CH3COONa(aq) + CO2(g) + H2O(l) Assume that the acid solution has the same density and specific heat capacity as water and that the mass of the final solution is 80.00 g. Calculate the molar enthalpy of reaction, ΔHr.
