Chapter 17, Problem 17.26QP

Interpretation Introduction

Interpretation: The isomer that has largest molar entropy, $S^{°}$ out of the three isomer of the hydrocarbon ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}$ is to be identified.

Concept introduction: The isomers have different geometrical arrangement or a difference in bonding, but with the same chemical formula.

Molar entropy is defined as the entropy change at standard condition of temperature and pressure for one mole of a substance.

To identify: The isomer that has largest molar entropy, $S^{°}$ out of the three isomer of the hydrocarbon ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}$.
