Question

explain entropy as a
thermodynamic state function
and apply it for spontaneity;​

Answer 1

Answer:

The second law of thermodynamics states that the total entropy of the universe always increases for a spontaneous process. • The net change in entropy of the system, ∆S , equals the sum of the entropy created during the spontaneous process and the change in energy associated with the heat flow.

hope this answer is helpful for you.

Answer 2

Answer:

The second law of thermodynamics states that the total entropy of the universe always increases for a spontaneous process. • The net change in entropy of the system, ∆S , equals the sum of the entropy created during the spontaneous process and the change in energy associated with the heat flow.

Explanation:

The best indicator of spontaneity in a reaction is the change in Entropy (S or DS). The Second Law of Thermodynamics states that for a reaction to be spontaneous, there must be an increase in entropy. Entropy is often defined as a measure of the disorder of a system, this is not a very accurate definition.
