Chapter 15, Problem 11RE

Interpretation Introduction

Interpretation:

The standard entropy change $\left(\Delta S^{°}\right)$ is to be calculated, and the positive sign expected in view of the nature of the reaction is to be explained.

Concept introduction:

Entropy $\left(\Delta S^{°}\right)$ is the randomness of system, which means the number of ways by which a substance can be arranged.

Enthalpy $\left(\Delta H^{°}\right)$ is equal to the sum of internal energy and the product of pressure and volume of the system.

$\Delta G^{°}$ is the actual free energy. It is a thermodynamic function, and is also known as Gibb’s free energy.
