1Increasing the concentration of a reactant shifts equilibrium to the right.

2For H₂ + I₂ ⇌ 2HI, the equilibrium concentrations are [H₂] = 0.1, [I₂] = 0.25 and [HI] = 0.6 mol/dm³. Find Kc.

3The French chemist whose principle predicts shifts in equilibrium was Henri Le ___.

4Adding acid to the yellow chromate equilibrium 2CrO₄²⁻ + 2H⁺ ⇌ Cr₂O₇²⁻ + H₂O turns the solution

5Removing ammonia as it forms in the Haber process

6At equilibrium, the forward and backward reactions continue.

7For N₂ + 3H₂ ⇌ 2NH₃ (ΔH negative), increasing the temperature

8The expression for Kc for 2SO₂ + O₂ ⇌ 2SO₃ is

9A catalyst increases the yield at equilibrium.

10Equilibrium can only be reached in a closed system.
