I had been asked this question in a national level competition.

The question is from Gas Liquid Equilibrium topic in portion Contact Equilibrium Separation Process of Food Processing Unit Operations

Answer 1

Correct answer is (b) Henry’s law

For explanation I would say: The main application of Henry’s law in respiratory physiology is to forecast gas dissolving in the alveoli and bloodstream during the gas exchange. The amount of oxygen that dissolves into bloodstream is proportional to the partial pressure of oxygen in alveolar air.
