At 298 K, for the reaction 2 PCl 3 (g) + O 2 (g) 2 POCl

Question:

At 298 K, for the reaction 2 PCl3(g) + O2(g) → 2 POCl3(l), ΔrH° = -620.2 kJ mol-1 and the standard  molar entropies, in J mol–1 K–1, are PCl3(g), 311.8; O2(g), 205.1; and POCl3(l), 222.4. Determine 

(a) ΔrG° at 298 K and 

(b) Whether the reaction proceeds spontaneously in the forward or the reverse direction when reactants and products are in their standard states.
