Work Step by Step
Using Henry's constant data for a gas dissolved in a liquid, the mole fraction of the gas dissolved in the liquid at the interface at a specified temperature can be determined from Henry's law expressed as
$$
y_{\mathrm{i}, \text { Liquid side }}(0)=\frac{P_{\mathrm{i}, \text { gas side }}(0)}{H}
$$where $H$ is Henry's constant and $P_{\mathrm{i} \text {,gas side }}(0)$ is the partial pressure of the gas $i$ at the gas side of the interface. This relation is applicable for dilute solutions (gases that are weakly soluble in liquids).
