The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.
According to that, $\Delta S$ of the universe should always be positive for a spontaneous reaction to occur. But what is the reason for that?
In Advanced Chemistry, Philip Matthews states:
Pg-287 This result cannot be proved; rather it is a statement of experiment
While there is true reasons for every point in chemistry, I feel there should be a real reason for it rather than experimental statement. But I searched it on Google but can't to find an answer. So, can you help me to give the reason?
