The following are at constant T and P. The conditions described in (a) and (b) below are initial conditions. Calculate Qc and CLEARLY indicate, with an arrow (“?”, or “?”) to which side the reaction must shift in order to attain equilibrium.

(a) A 250.0-mL flask containing 0.0250 mol of NO(g), 0.0100 mol of Cl2(g), and 0.250 mol of

NOCl: 2NO(g) + Cl2(g) ⇌ 2NOCl(g) Kc = 4.6 × 104

(b) A 5.00-L flask containing 35.0 g of NH3, 20.0 g of N2, and 15.5 g of H2:

N2(g) + 3H2(g) ⇌ 2NH3(g) Kc = 0.060
