Calculate the enthalpy change involved in the precipitation reaction between 50ml of 0.1 M lead nitrate solution and 50ml of 0.1 M sodium chloride solution at a constant temperature of 25°C. The balanced chemical equation for the reaction is Pb(NO3)2 + 2NaCl → PbCl2 + 2NaNO3. Standard enthalpies of formation for Pb(NO3)2, NaCl, PbCl2, and NaNO3 are -460.56 kJ/mol, -407.33 kJ/mol, -359.57 kJ/mol, and -467.93 kJ/mol respectively.
