Chapter 5, Problem 5B.1ST

Interpretation Introduction

Interpretation:

The composition of a solution in terms of the fraction of molecules that are B in which two isomers A and B are in equilibrium ($\text{A}\rightleftharpoons \text{B}$) at ${\text{37}}^{\text{°}}\text{C}$ and ${\text{Δ}}_{\text{r}}{\text{G}}^{\sout{\text{ο}}}\text{= -2}{\text{.2 kJ mol}}^{\text{-1}}$ has to be estimated.

Concept Introduction:

Fraction can be defined as the ratio of the concentration of one isomer to the total concentration of solutes.  As fraction is expressed in terms of concentration, it is related to equilibrium $\text{K}$.
