Question

what is the best accepted definition for Henry's Law in boards (class 12). ???​

Answer 1

the one in ncert is correct

Answer 2

The law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas.

The most commonly used version of Henry's law is: "The partial pressure of a gas in vapour phase (p) is proportional to the mole fraction of the gas (χ) in a solution."

p ∝ χ

p =KH χ

Where KH = Henry's law constant.
