A pipeline containing \(99.0 \mathrm{~mol} \%\) ammonia and \(1.0 \mathrm{~mol} \%\) hydrogen gas is vented to ambient air via a \(15 \mathrm{~m}\) long, \(3.5 \mathrm{~mm}\) diameter tube. Temperature and pressure everywhere are \(0^{\circ} \mathrm{C}\) and \(101,325 \mathrm{~Pa}\), respectively. Assume \(99.0 \mathrm{~mol} \%\) ammonia and \(1.0 \mathrm{~mol} \%\) hydrogen at the pipeline and pure air at the air end of the tube. Ideal gas, \(D_{\mathrm{AB}}=1.98 \times 10^{-5} \mathrm{~m}^{2} / \mathrm{s}\left(\mathrm{A}=\right.\) ammonia, \(\mathrm{B}=\) air at \(\left.0^{\circ} \mathrm{C}\right), D_{\mathrm{CB}}=6.11 \times 10^{-5} \mathrm{~m}^{2} / \mathrm{s}(\mathrm{C}=\)

hydrogen, \(\mathrm{B}=\) air at \(\left.0^{\circ} \mathrm{C}\right), D_{\mathrm{CA}}=7.48 \times 10^{-5} \mathrm{~m}^{2} / \mathrm{s}(\mathrm{A}=\) ammonia, \(\mathrm{C}=\) hydrogen at \(\left.0^{\circ} \mathrm{C}\right)\).

What are the molar fluxes, \(\mathrm{mol} /\left(\mathrm{s}^{2}\right)\), of ammonia, hydrogen, and air?
