Por the reaction ${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{HI}\left(\mathrm{g}\right)$, the equilibrium can be shifted in favour of product by

• A

  Increasing the [H₂]

• B

  Increasing the pressure

• C

  Increasing the [I₂]

• D

  By using the catalyst
