the laboratory, POCl3 (phosphorus oxychloride) is used in the manufacture of phosphate esters, which are used in flame retardants and pesticides. It can be prepared by the following reaction at 25°C: 2 PCl3 (g) + O2 (g) --> 2 POCl3 (g) DH° = - 572 kJ; DG° = - 518.7 kJ Calculate DS°. Is the sign reasonable? Calculate S° for POCl3. Calculate DHf° for POCl3
