Question 1

Consider the following reversible reaction:

POCl₃(g)

POCl(g) + Cl₂(g) K_c = 0.450

The following initial amounts of reactants and products were mixed: [POCl₃] = 0.750 M, [POCl] = 0.550 M, and [Cl₂] = 0.150 M. What is the equilibrium concentration of POCl?
◦ 0.395 M
◦ 0.155 M
◦ 0.740 M
◦ 0.945 M
◦ 0.360 M

Question 2

Consider the reaction:

2 SO₂(g) + O₂(g)

2 SO₃(g), Δ_rH° = -196.6 kJ/mol

The equilibrium is displaced to the left if:
◦ some sulfur trioxide is removed
◦ the temperature is raised
◦ some sulfur dioxide is added
◦ the pressure is raised
◦ the temperature is lowered
