Chapter 17, Problem 17.79QP

Interpretation Introduction

Interpretation:

It should be determine the two ways that could measure standard free $\text{ΔG}°$ energy of a reaction.

Concept Information:

Thermodynamics is the branch of science that relates heat and energy in a system.  The four laws of thermodynamics explain the fundamental quantities such as temperature, energy and randomness in a system.  Entropy is the measure of randomness in a system.  For a spontaneous process there is always a positive change in entropy.  Free energy (Gibbs free energy) is the term that is used to explain the total energy content in a thermodynamic system that can be converted into work.  The free energy is represented by the letter G.  All spontaneous process is associated with the decrease of free energy in the system.  In non-spontaneous reaction there is an increase of free energy in the system.
