The formula to calculate Activity Coefficient (y) is:
\[ y = \frac{a}{x} \]
Where:
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.
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.
