Chapter 7.1, Problem 7.2PP

Interpretation Introduction

Interpretation:

The sign of $\text{ΔG}$ and spontaneity of water formation from Hydrogen and Oxygen has to be given.

Concept Introduction:

Gibbs free energy:

In thermodynamics, the free energy change of system is given by subtraction of product of temperature and entropy change from enthalpy.

    $\text{ΔG}\text{=}\text{ΔH-TΔS}$

Where,

  $\text{ΔG}$ is free energy change

  $\text{ΔH}$ is enthalpy change

  $\text{ΔS}$ is entropy change

  $\text{T}$ is temperature
