Chapter 5, Problem 5A.1ST

Interpretation Introduction

Interpretation:

For the given esterification reaction, reaction quotient has to be written.

Explanation of Solution

Given reaction,

${\text{CH}}_{\text{3}}\text{COOH}\text{+}{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}\stackrel{}{\to }{\text{CH}}_{\text{3}}{\text{COOC}}_{\text{2}}{\text{H}}_{\text{5}}\text{+}{\text{H}}_{\text{2}}\text{O}$

Write the reaction quotient for the given reaction,

$\begin{array}{l}\text{reaction}\text{quotient}\left(\text{Q}\right)\text{=}\frac{\left[\text{products}\right]}{\left[\text{reactants}\right]}\\ \\ \text{Q}\text{=}\frac{\left[{\text{CH}}_{\text{3}}{\text{COOC}}_{\text{2}}{\text{H}}_{\text{5}}\right]\left[{\text{H}}_{\text{2}}\text{O}\right]}{\left[{\text{CH}}_{\text{3}}\text{COOH}\right]\left[{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}\right]}\end{array}$

Therefore, reaction quotient for the reaction is $\text{Q}\text{=}\frac{\left[{\text{CH}}_{\text{3}}{\text{COOC}}_{\text{2}}{\text{H}}_{\text{5}}\right]\left[{\text{H}}_{\text{2}}\text{O}\right]}{\left[{\text{CH}}_{\text{3}}\text{COOH}\right]\left[{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}\right]}$
