Calculate Activity Coefficient (y)



Formula

The formula to calculate Activity Coefficient (y) is:

\[ y = \frac{a}{x} \]

What is an Activity Coefficient?

An activity coefficient is defined as the ratio of total activity to the mole fraction of a substance in a mixture of 2 or more chemical substances. It provides insight into the behavior of substances in mixtures, particularly in non-ideal solutions.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Activity Coefficient:

\[ y = \frac{0.8}{0.4} = 2 \]

The Activity Coefficient (y) is 2.
