Answer to Question #333902 in General Chemistry for yow

Question

The decomposition of PCl5 is shown below:

PCl5(g)⇌ PCl3(g) + Cl2(g) Kc = 0.029 at 85°C

Find out if the reaction proceeds forward, backward, or if the system is at equilibrium when a 1 liter

container is filled with 0.4 mole PCl5, 0.5 mole PCl3, and 0.2 mole Cl2.

Answer 1

∆G>0, the reaction proceeds backward
