In a binary gas-liquid system, $N_{A, E M D}$ is the molar flux of a gas $A$ for equimolar counter diffusion with a liquid $B . N_{A, U M D}$ is the molar flux of $A$ for steady onecomponent diffusion through stagnant $B$. Using the mole fraction of $A$ in the bulk of the gas phase as $0.2$ and that at the gas-liquid interface as 0.1 for both the modes of diffusion, the ratio of $N_{A, U M D}$ to $N_{A, E M D}$ is equal to________________(rounded off to two decimal places).
