QuestionWhat happens to the equilibrium when $\mathrm{HI}$ gas is added to the system: A, B, C, or D? $$51.8 \mathrm{~kJ}+\mathrm{H}_{2}(\mathrm{~g})+\mathrm{I}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{g})$$

Studdy Solution
Therefore, the reaction shifts to the left (reactants) and the concentrations of $\mathrm{H}_{2}$ and $\mathrm{}_{2}$ increase.So, the correct answer is D. The reaction shifts to the left (reactants) and the concentrations of $\mathrm{H}_{2}$ and $\mathrm{}_{2}$ increase.
