Chemical Kinetics

Find the rate law for the reaction, \(\mathrm{CHCl}_{3(\mathrm{~g})}+\mathrm{Cl}_{2(\mathrm{~g})} \rightarrow \mathrm{CCl}_{4(\mathrm{~g})}+\mathrm{HCl}_{(\mathrm{g})}\) if order of reaction with respect to \(\mathrm{CHCl}_{\mathrm{a}(\mathrm{g})}\) is one and \(\frac{1}{2}\) with \(\mathrm{Cl}_{2(\mathrm{~g})}\).
