Question
Chapter 18, Problem 18.27CP
Interpretation Introduction
Interpretation:
The given query can be solved using the second law of
Concept introduction: Second law of thermodynamics postulates that the entropy of the isolated system can never decrease with time. The entropy of the system is constant in cases where the system remains in an equilibrium, or undergoes a reversible reaction. The value of entropy always increases in case of spontaneous process, and these processes are irreversible.
Given: Here, we are given a system containing two bulbs filled with ideal gases and separated by a stop cock. If the stop cock is opened, what will be the nature of ?H, ?S, and ?G (+, -, or zero) for the reaction. We have to explain how this reaction describes the second law of thermodynamics and what is the nature of the process (spontaneous or nonspontaneous).
