Consider the reaction
2POCl₃
(g) → 2PCl₃
(g) +O₂
(g)
a. Calculate ΔG° for this reaction. The ΔG°_f
values for POCl₃(g) and PCl₃(g) are -502 kJ/mol and -270. kJ/mol,respectively.
b. Is this reaction spontaneous under standard conditions at 298 K?
c. The value of 6S' for this reaction is 179 J/K mol .At what temperatures
is this reaction spontaneous at standard conditions? Assume that ΔH°
and ΔS°' do not depend on temperature.
