Which of the following should have the smallest Henry's law constant (k_H) in water at 25 °C? A) O₂ B) CO₂ C) N₂ D) He E) NH₃

Question

Quizplus · Accepted Answer

Henry's law constant is related to the solubility of a gas in a liquid. The smaller the size of the gas molecule, the less soluble it is in water. Therefore, the gas with the smallest molecule size, which is helium (He), should have the smallest Henry's law constant in water at 25 °C.
