Chapter 2, Problem 6P

Summary Introduction

To examine: Whether the statement, “The criterion for whether a reaction proceeds spontaneously is ΔG not ΔG°, because ΔG takes into account the concentrations of the substrates and products.” is true or false.

Concept introduction:

The ΔG is represented by the free energy change of spontaneously proceeding reaction and ΔG° represent the standard free energy rate and it also take the concentrations of the reacting compounds into account. If in a reaction the standard free energy rate (ΔG°) is negative, the reaction would not proceed spontaneously and there is a huge amount of product present. If in a reaction the ΔG° is positive the reaction is spontaneously proceeds to the forward condition and the amount of substrate is excess.
