Which of the following should have the largest 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 dependent on the gas solubility and the gas pressure. The gas solubility depends on the intermolecular forces between the gas and the solvent molecules. Larger and more polar molecules with stronger intermolecular forces will have a higher Henry's law constant. Among the given choices, E (NH₃) is the largest and most polar molecule with the strongest intermolecular forces, making it the best choice for having the largest Henry's law constant in water at 25 °C.
