Question
The Henry's law constant ($K_H$) of $CO_2$ in water at $298\text{ K}$ is $5/3\text{ kbar}$. If the partial pressure of $CO_2$ above the water surface is maintained at $0.01\text{ bar}$, find its mole fraction in the resulting solution.
Answer: A
💡 Solution & Explanation
Using the relation $P = K_H \times \chi$. First, convert the pressure to consistent units: $0.01\text{ bar} = 10^{-5}\text{ kbar}$. The mole fraction $\chi = \frac{10^{-5}}{5/3} = 0.6 \times 10^{-5} = 6 \times 10^{-6}$.
