For NH₄HS(s) ⇌ NH₃(g) + H₂S(g), Kp = 0.11 bar² at 298 K. A rigid flask at 298 K holds ammonia at a pressure of 0.40 bar. Plenty of solid NH₄HS is put in, so that some solid is left at equilibrium. What is the total pressure in the flask at equilibrium?

← For N₂(g) + 3 H₂(g) ⇌ 2 NH₃(g), Kc = 0.50 L² mol⁻² at a certain temperature. A 2.00 L vessel at that temperature holds 1.00 mol of N₂, 2.00 mol of H₂ and 0.400 mol of NH₃. Which statement about this mixture is correct?Carbon dioxide is passed over hot coke: C(s) + CO₂(g) ⇌ 2 CO(g), with Kp = 2.4 bar at the temperature used. The gas is held in a cylinder whose piston keeps the total pressure at 2.00 bar, and some coke is left at equilibrium. What is the percentage of carbon monoxide in the gas at equilibrium, by moles? Give it to the nearest integer. →
