QuestionHow can you increase the formation of $\mathrm{Cl}_{2}$ in this reaction?
$$4 \mathrm{HCl}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})+2 \mathrm{Cl}_{2}(\mathrm{~g})+203 \mathrm{~kJ}$$
A. remove $\mathrm{HCl}$ B. increase the volume C. add $\mathrm{H}_{2} \mathrm{O}$ D. cool the system
