摘要
The enthalpy of coordination reaction of manganese chloride with p toluidime has been determined by solution calorimetry in a new model isoperibol reaction calorimeter.The calorimetric solvent is a solution consisting of 3.0 mol·L -1 HCl and ethyl alcohol absolute.A new thermochemical cycle has been designed to determine the standard enthalpy of formation for Mn(p tol) 2Cl 2.According to the results,we obtained the values: Δ r H m=19.149kJ·mol -1 ,Δ f H m[Mn(p tol) 2Cl 2,s]=-590.748kJ·mol
