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?

What is the effect of adding a catalyst on the equilibrium position of a redox reaction where iodate ions combine with sulfite ions in an acidic solution to create iodide ions and sulfate ions? Calculate the new equilibrium constant with and without the catalyst given the reaction equation: IO3^- (aq) + 3SO3^2- (aq) + H2O (l) → I^- (aq) + 3SO4^2- (aq) + 2H+ (aq) Assume the temperature, pressure and volume remain constant, and that the initial concentrations of each reactant and product are known.
