## Example Formula

The formula to calculate the liquid phase coefficient (γ) in dilute solutions can be given by:

γ = φB × MB × T / (ηB × VA)

Where:

1. γ is the liquid phase coefficient.
2. φB is the association factor of solvent B.
3. MB is the molecular weight of solvent B.
4. T is the absolute temperature (in Kelvin).
5. ηB is the viscosity of solvent B.
6. VA is the molal volume of solute A.

## Who wrote/refined the formula

The concept of the activity coefficient was developed over time by various scientists in the field of physical chemistry and thermodynamics. It was Lewis who in 1907 introduced the term "activity" and defined the activity coefficient.

## Real Life Application

The concept of the liquid phase coefficient is used widely in the field of chemical engineering and industrial processes. For example, in the design of distillation columns and in the synthesis of chemical reactions, where it's crucial to predict how components in a solution will behave.

## Key individuals in the discipline

Gilbert N. Lewis, an American physical chemist, was known for his work on chemical thermodynamics. His introduction of the term "activity" and the definition of the activity coefficient have been a significant influence in this field.
