We wish to strip \(\mathrm{SO}_{2}\) from water using pure air at \(20.0^{\circ} \mathrm{C}\). Outlet water contains \(0.0060 \mathrm{~mol} \% \mathrm{SO}_{2}\), and inlet water contains \(0.112 \mathrm{~mol} \% \mathrm{SO}_{2}\). Operation is at 0.72 bar, and \(\mathrm{V}=1.2 \times \mathrm{V}_{\text {min }} . \mathrm{H}_{\mathrm{OL}}=0.98 \mathrm{~m}\) and the Henry's law constant is \(22,500 \mathrm{~mm} \mathrm{Hg} / \mathrm{mole}\) fraction \(\mathrm{SO}_{2}\).

a. Calculate the packing height required, \(\mathrm{y}_{\text {out }}\), and \(\mathrm{V}\) if \(\mathrm{L}=5\) \(\mathrm{mol} / \mathrm{min}\).

b. Calculate the packing height required, \(\mathrm{y}_{\text {out }}\), and \(\mathrm{V}\) if \(\mathrm{L}=15\) \(\mathrm{mol} / \mathrm{min}\).
