Forces That Drive Reactions - Entropy

Forces That Drive Reactions - Entropy. Entropy (?S). Entropy is a measure of disorder Matter tends to attain minimum potential energy = Enthalpy. Matter tends to attain maximum randomness = Entropy. Entropy ? least organized, most random state possible. ?S Formula.

entropy - is a measure of disorder

entropy - is a measure of disorder. or the amount of chaos or randomness. disorder, being relative, needs a standard to measure against. so any substance at absolute zero (0 K) is given a value of 0 joule/mol . K. vaporization. gas. liquid. solid. entropy. melting. 0k. temperature.
