Chapter 22, Problem 53AP

Interpretation Introduction

Interpretation:

The equilibrium concentration of ${\left[\text{Pb(EDTA)}\right]}^{2-}$ is to be determined.

Concept introduction:

The reaction quotient is the ratio of molar concentration of the ions or the partial pressure of the gaseous atoms or molecules in the product side to the gaseous atoms and molecules in the reactant side, raised to the power of their stoichiometric coefficient in the balanced chemical reaction.

For a general chemical reaction, $\text{aA + bB }\underset{}{\overset{}{\rightleftarrows }}\text{cC+dD}$, the reaction quotient will be represented as

$\text{Q = }\frac{{\text{[C]}}^{\text{c}}{\text{[D]}}^{\text{d}}}{{\text{[A]}}^{\text{a}}{\text{[B]}}^{\text{b}}}$

Here, $Q$ is the reaction quotient.
