Reversible reactions and equilibrium — practice question

Ammonia is manufactured by the Haber process at a temperature of $400\,^{\circ}\text{C}$ and a pressure of $20\,000\,\text{kPa}$. The temperature is then raised to $500\,^{\circ}\text{C}$ while the pressure remains unchanged. What effects will this change have on ammonia production?

  • AIt is made at an increased rate and the position of the equilibrium moves to the left.
  • BIt is made at an increased rate and the position of the equilibrium moves to the right.
  • CIt is made at a decreased rate and the position of the equilibrium moves to the left.
  • DIt is made at a decreased rate and the position of the equilibrium moves to the right.
