Chapter 18, Problem 93AP

Interpretation Introduction

Interpretation:

The signs of $\Delta S$, $\Delta H$, and $\Delta G$, when hydrogen gas is absorbed onto the surface of Niareto bedetermined.

Concept introduction:

Entropy $\left(S\right)$ is the randomness of the system, which refers to the number of ways a substance can be arranged.

Enthalpy equals to the addition of internal energy and product of pressure and volume of the given system. It is denoted as $H$.

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