Chemistry - Chemical Equilibrium Question with Solution | TestHub

In the reaction$\mathrm{C}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{C}\mathrm{O}\left(\mathrm{g}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)$
$\mathrm{\Delta }{\mathrm{n}}_{\mathrm{g}}>0$, hence the reaction will shift in forward direction by increasing volume (or lowering the pressure).
