Reversible reactions and equilibrium — practice question

Ammonia is manufactured by the Haber process. The equation is given below. $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g)$ The forward reaction releases heat. Which statement is correct?

  • AIncreasing pressure decreases the yield of ammonia, but speeds up the reaction.
  • BIncreasing temperature decreases the yield of ammonia, but speeds up the reaction.
  • CIncreasing the concentration of hydrogen and nitrogen results in a lower yield of ammonia.
  • DIncreasing the temperature increases the yield of ammonia and speeds up the reaction.
