PCl5, PCl3 and Cl2 are at equilibrium at 500K and having concentration

1.	PCl5, PCl3 and Cl2 are at equilibrium at 500K and having concentration 1.59 M PCl3, 1.59 M Cl2 and 1.41 M PCl5. Calculate KC for the reaction, PCl5 ⇌ PCl3 + Cl2.
Answer» For the reaction, PCl₅ ⇌ PCl₃ + Cl₂ Equilibrium constant = K_c = \(\frac{[PCl_3][Cl_2]}{[PCl_5]}\) = \(\frac{(1.59)\times(1.59)}{(1.41)}\) = 1.79

Answer»

For the reaction, PCl₅ ⇌ PCl₃ + Cl₂

Equilibrium constant = K_c = \(\frac{[PCl_3][Cl_2]}{[PCl_5]}\)

= \(\frac{(1.59)\times(1.59)}{(1.41)}\)

= 1.79
