Consider the reaction: 2H2O (g) ⇄ 2H2 (g) + O2 (g) At 1000 K, the equilibrium constant Kc for this reaction is 4.17 x 10^-5. Suppose that initially, 0.10 moles of H2O, 0.20 moles of H2, and 0.20 moles of O2 are placed in a 1.0 L container at 1000 K. What will be the equilibrium concentrations of H2O, H2, and O2?

A chemistry student needs to determine the effect on the equilibrium position of a chemical reaction when the concentration of a reactant is decreased. The student is given the balanced equation: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + heatIf the concentration of H₂ is decreased by removing 50% of its concentration, what would be the effect on the concentration of N₂, NH₃, and the position of equilibrium?
