Statistical Entropy

Statistical Entropy is the application of probability theory to the principle of entropy showing that entropy is a measure of the amount of disorder in a system. It is based on the probability of molecular positions.

The number of possible ways for a given condition to occur called equivalent microstates is denoted as W.

Entropy is denoted as S.

k is the Boltzmann Constant = 1.38 X 10-23 JL-1

S = k ln W

This shows that entropy is a measure of the disorder of a system.
