Calculate the standard enthalpy change of the precipitation reaction between 50.0 mL of 0.100 M Pb(NO3)2 and excess 0.100 M NaCl solution at 25°C given that the reaction is Pb(NO3)2 (aq) + 2NaCl (aq) → PbCl2(s) + 2NaNO3 (aq) and the enthalpy of formation of NaNO3 (aq) and NaCl (aq) are -467.7 kJ/mol and -411.2 kJ/mol respectively.
