Chapter 15, Problem 15.29QP

Interpretation Introduction

Interpretation:

The total pressure of the mixture is whether less than or greater than the sum of the initial pressures has to be identified using the given data.

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

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

Equilibrium constant at constant pressure:$K_p$

It is used to express the relationship between product pressures and reactant pressures.

  For a general reaction, $\text{aA+bB}\rightleftarrows \text{cC+dD}$

$\text{Equilibrium}\text{constant}{\text{K}}_p\text{=}\frac{P_C{}^{\text{c}}{P}_D{}^{\text{d}}}{P_A{}^{\text{a}}{P}_B{}^{\text{b}}}$
