Chapter 17, Problem 17.90

(choose chapter or problem)

Consider the reaction 2POCl3 1g2 h 2PCl3 1g2 1 O2 1g2 a. Calculate DG8 for this reaction. The DGf 8 values for POCl3(g) and PCl3(g) are 2502 kJ/mol and 2270. kJ/mol, respectively. b. Is this reaction spontaneous under standard conditions at 298 K? c. The value of DS8 for this reaction is 179 J/K mol. At what temperatures is this reaction spontaneous at standard conditions? Assume that DH8 and DS8 do not depend on temperature.
