Henry's law states that for a gas dissolved in a liquid the solubility is
Ainversely proportional to temperature (typical)
Bindependent of pressure
Cdirectly proportional to the partial pressure of the gas
Dproportional to the square of pressure
Answer & Solution
Correct answer: C. directly proportional to the partial pressure of the gas
1. Henry's law: p = K_H · x where p is partial pressure and x is the mole fraction of dissolved gas.
2. Hence solubility (x) ∝ partial pressure p at a given temperature.
3. The proportionality constant K_H is characteristic of the gas-solvent pair.
