Chapter 4.7, Problem 1E

(A)

Interpretation Introduction

Interpretation:

The process is reversible or irreversible process

Concept Introduction:

Reversible Process:

The process in which both the direction and sustains thermodynamic equilibrium through the surroundings is known as reversible process. By initiating insignificant changes to some property through environment the process can be overturn.

Irreversible Process:

The process that occurs through only one direction and also it will not sustain the thermodynamic equilibrium with the surroundings is the irreversible process. The entropy of the process is increased and the changed entropy will be the same for both reversible and irreversible process.
