Given the following reaction at equilibrium: \( \mathrm{PCl}_{3(g)}+\mathrm{Cl}_{2(g)} \rightleftarrows \mathrm{PCl}_{5(g)} \quad \Delta \mathrm{H}=-45 \mathrm{~kJ} / \mathrm{mol} \) of \( \mathrm{PCl}_{5(g)} \) The amount of \( \mathrm{PCl}_{(0)} \) in the system can be increased by: (a) decreasing the concentration of \( \mathrm{Cl}_{2} \) at constant temperature and pressure (b) increasing the temperature at constant pressure (c) adding a catalyst at constant temperature and pressure (d) increasing the pressure at constant temperature (e) injecting some He gas
