Chapter 3, Problem 3.30P

Interpretation Introduction

(a)

Interpretation:

The standard free energy for dissociation of fluoroacetic acid is to be predicted.

Concept introduction:

The relation between standard free energy of ionization $\text{Δ}{G}_{\text{a}}^{\circ }$ and dissociation constant $K_{\text{a}}$ is given by an expression shown below.

$\text{Δ}{G}_{\text{a}}^{\circ }=2.3RT\left(\text{p}{K}_{\text{a}}\right)$

Where,

• $R$ is the Gas constant.

• $T$ is the absolute temperature in Kelvin.

• $K_{\text{a}}$ is the dissociation constant.
