Question

Behaviour of vapour can be determined by which law ?

Answer 1

Figure 1: Positive non-ideal behavior of the vapor pressure of a solution follows Henry's Law at low concentrations and Raoult's Law at high concentrations (pure).

Answer 2

Answer:

Behaviour of vapour can be determined by Henry's Law.

Explanation:

Henry's Law:-It is  one of the gas laws formulated by William Henry in 1803 which states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

C=kPgas

where

C is the solubility of a gas at a fixed temperature in a particular solvent (in units of M or mL gas/L)

k  is Henry's law constant (often in units of M/atm)

Pgas  is the partial pressure of the gas (often in units of atm)
