Chapter 19, Problem 39QRT

Interpretation Introduction

Interpretation:

The reaction ${\text{F}}_{\text{2}}\text{(g)}\text{+}{\text{2Br}}^{\text{-}}\text{(aq)}\stackrel{}{\to }{\text{2F}}^{\text{-}}\text{(aq)}\text{+}{\text{Br}}_{\text{2}}\text{(l)}$ is product favored or not has to be determined.

Concept Introduction:

$E{°}_{\text{cell}}$ value can be used to determine whether the reaction is product favored or not.  $E{°}_{\text{cell}}$ value can be calculated using the formula shown below,

    $E{°}_{\text{cell}}=E{°}_{\text{cathode}}-E{°}_{\text{anode}}$

If the $E{°}_{\text{cell}}$ value is obtained as positive then the reaction is product-favored and if the $E{°}_{\text{cell}}$ value is negative, the reaction is not product-favored.
