Equilibria — practice question

At $764\,\text{K}$ and $141\,\text{kPa}$, a sample containing $17.15\,\text{mol}\,\text{HI}(g)$ is in dynamic equilibrium with $2.27\,\text{mol}\,\text{H}_2(g)$ and $2.84\,\text{mol}\,\text{I}_2(g)$ in a volume of $1\,\text{m}^3$. $\text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g)$ For this mixture, two equilibrium constants, $K_c$ and $K_p$, can be worked out. Which of the following statements about these equilibrium constants is correct?

  • A1, 2 and 3 are correct
  • B1 and 2 only are correct
  • C2 and 3 only are correct
  • D1 only is correct
