diffusivity of $C{O}_2$ in this mixture is approximately $0\mathrm{.}2{10}^{-4}\frac{m^2}{s}.$ What will be the molecular diffusivity of $C{O}_2$ in liquid water containing $1$mol$\%$ Ammonia at $P=1$atm and $T=298K.$

$($a$)$ equal to $0\mathrm{.}2{10}^{-3}\frac{m^2}{s}($approx$.)$

$($b$)$ equal to $0\mathrm{.}2{10}^{-4}\frac{m^2}{s}($approx$.)$

$($c$)$ equal to $0\mathrm{.}20{10}^{-8}\frac{m^2}{s}($approx$.)$

$($d$)$ equal to $0\mathrm{.}2{10}^{-5}\frac{m^2}{s}($approx$.)$

For the diffusion of gases A and $B,$ the flux of $A$ is given by $N_A=-c{D}_{AB}\frac{d(x_A)}{dz}+\frac{c_A}{c}(N_A+N_B).$ For the diffusion of gas $C$ through the stagnant non$-$diffusing gas $B,$ the flux of $C(N_C)$ is given by$,$

$\backslash$table$[[(a)-c{D}_{CB}\frac{d(x_B)}{dz}+\frac{c_C}{c}(N_B)$
