Reversible reactions and equilibrium — practice question

Samples of nitrogen and hydrogen are mixed and left until equilibrium is reached. The equation is given as: $\text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3 \qquad \Delta H = -92\,\text{kJ mol}^{-1}$. The temperature is raised and a new equilibrium is then established. Which statement about this new equilibrium is correct?

  • AThe amount of product increases.
  • BThe amount of product decreases.
  • CThe rate of the forward reaction is greater than the rate of the reverse reaction.
  • DThe rate of the forward reaction is less than the rate of the reverse reaction.
