Reversible reactions and equilibrium — practice question

Two gases, X and Y, combine to produce a gas Z, as shown. $\text{X(g)} + 3\text{Y(g)} \rightleftharpoons 2\text{Z(g)} \quad \Delta H = -92\,\text{kJ mol}^{-1}$ Which alteration in the conditions would increase both the reaction rate and the equilibrium amount of Z?

  • Adecrease concentration of X
  • Bincrease pressure
  • Cincrease temperature
  • Duse a catalyst
