Chapter 19, Problem 19.60QE

Interpretation Introduction

Interpretation:

Equilibrium of ${{\text{[Fe(H}}_{\text{2}}{\text{O)}}_{\text{6}}\text{]}}^{\text{3}+}$ complex formation has to be written and determination of number of unpaired electrons without an experiment has to be explained.

Concept Introduction:

Equilibrium constant:

At equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K.

For a general reaction,

  $\text{aA+bB}\rightleftarrows \text{cC+dD}$

  $\text{Equilibrium}\text{constant}\text{K}\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}{\left[\text{B}\right]}^{\text{b}}}$
