Chapter 15, Problem 15.54QP

Interpretation Introduction

Interpretation:

The concentration of each species when the reaction in diagram (b) reaches equilibrium has to be stated.

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

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

• Molarity (M): Molarity is number of moles of the solute present in the one litter of the solution.

$\text{Molarity (M) =}\frac{\text{Number}\text{of}\text{moles}\text{of}\text{solute}}{\text{1}\text{liter}\text{of}\text{solution}}$
