Equilibria — practice question

For which equilibrium will raising the pressure while keeping the temperature constant increase the yield of the products on the right-hand side of the equation?

  • A$\text{CaCO}_3(s) \rightleftharpoons \text{CaO}(s) + \text{CO}_2(g)$
  • B$4\text{HCl}(g) + \text{O}_2(g) \rightleftharpoons 2\text{H}_2\text{O}(g) + 2\text{Cl}_2(g)$
  • C$2\text{HI}(g) \rightleftharpoons \text{H}_2(g) + \text{I}_2(g)$
  • D$3\text{Fe}(s) + 4\text{H}_2\text{O}(g) \rightleftharpoons \text{Fe}_3\text{O}_4(s) + 4\text{H}_2(g)$
