Moles of NO = $\frac{600 \times 1 0^{- 3} \times 100}{30} = 2$

$∴$ moles of NO₂ = 2

3NO₂ + H₂O -> 2HNO₃ + NO

$0.2 M \frac{0.4}{3} M o r p H = - l o g \frac{0.4}{3} = 0.88$

^{$Z = \frac{P V_{m}}{R T} \Rightarrow 0.5 = \frac{24 \times V_{m}}{24}$}

^{$V_{m} = 0.5 l / m o l e$}

^{$(P + \frac{a}{V_{m}^{2}}) (V_{m} - b) = R T$}

^{$(24 + \frac{a}{0 . 5^{2}}) (0.5 - 0.1) = 24$}

^{$24 + \frac{a}{0 . 5^{2}} = 60$}

^{$\frac{a}{0 . 5^{2}} = 36$}

^{$a = 36 \times 0 . 5^{2} = 9 \frac{a t m - l^{2}}{m o l^{2}}$}
