In drop-solution calorimetry the enthalpy increment of the sample and its enthalpy of solution at the calorimetric temperature are determined. The difference in the enthalpy of solution of products and reactants gives the enthalpy of reaction at room temperature. This method has been used for the...

The standard enthalpy of solution of solid tri- n-dodecylammonium chloride in benzene at 303.15 K was found to be ΔH o(soln) = (90.00 ± 0.04) kJ mol 1 by direct solution calorimetry. This value was combined with auxiliary thermochemical data to derive the standard change of enthalpy on...
Is the heat of the solution of LiCl exothermic or endothermic? Determine the heat of reaction of the following chemical reaction using standard heats of formation. Then classify the reaction as endothermic or exothermic. 2SO3(g) arrow 2SO2(g) + O2(g) ...
By measurement of the enthalpies of solution of NaAlCl4(c), NaCl(c), and AlCl3(c) in 0.05 mol kg1 HCl the standard enthalpy of formation of NaAlCl4 has been determined to be ΔHfo(NaClCl4, c, 298.15 K) = (1139.45 ± 1.20) kJ mol1....
