Chapter 16, Problem 109QRT

Interpretation Introduction

Interpretation:

The statement that any reaction which is occurring at an appreciable rate with ${\Delta }_{\text{r}}G<0$, will proceed until all reactants are converted into products is to be criticized.

Concept Introduction:

According to Le Chatelier’s principle, an increase in the concentration of reactants makes the reaction proceed in forward direction.  However an increase in the products concentration makes the reaction proceed in backward direction.  Any change disturbing the equilibrium condition makes the reaction proceed in the direction in which the change can be undone.
