Step 1

The member of given pair with the higher entropy is to be chosen-

  1. 1 mol O2(g) or 1 mol O3(g) under equivalent conditions.
Step 2

Entropy is the measure of disorder or randomness in the molecule.

In general, Entropy of gases > entropy of liquids > entropy of solids.

Thus, greater is the motion of atoms, higher the entropy.

Step 3

A molecule can have three types of motion- translational, rotational, and vibrational motion.

As per the third law of thermodynamics, a pure crystalline substance has zero entropy at 0 Kelvin. As the temp...
