What information would you expect when equilibrium constant Kc > 1?

Why is backward reaction favoured when Kc < 1 ?

Write a chemical equilibrium in which Kc become equal to Kp.

Give the relationship Kp between Kc for the following reaction.

PCl₅ (g) ⇌ PCl₃ (g) + Cl₂ (g)

Write equilibrium constant Kc for the reaction.

CaCO₃ (s) + heat ⇌ CaO (s) + CO₂ (g)

How does the value of equilibrium constant(K) predict the direction of the chemical reaction?

Define active mass. How is it expressed?

Define equilibrium constant(Kc).
