Question
The Henry’s law constant (KH) values of the three gases (P, Q, R) in water are 69.16, 1.85 × 10–5 and 0.611 kbar respectively. The solubility of these gases in water follow the orderP > Q > RQ > R > PR > Q > PP > R > Q
Solution
According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. The constant of proportionality is the Henry's Law constant (KH). Therefore, a higher KH value means a higher solubility.
Given the KH values of the three gases P, Q, R are 69.16, 1.85 × 10–5 and 0.611 kbar respectively, the solubility of these gases in water would follow the order P > R > Q.
