Chapter 15, Problem 44E

Interpretation Introduction

Interpretation:

Equilibrium constant expression of each chemical reaction is to be written.

Concept Introduction:

In general equilibrium constant is a way by which relative concentration of reactants and products at equilibrium can be quantified.

The equilibrium constant is the ratio of concentrations of products to that of reactants each raised to the power of their respective stoichiometric coefficients.

For a chemical reaction.

$\text{aA}+\text{bB}\rightleftharpoons \text{cC}+\text{dD}$.

The equilibrium expression can be written as:

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

Here, $\left[\text{C}\right]$, $\left[\text{D}\right]$ are concentration of products and $\left[\text{A}\right]$, $\left[\text{B}\right]$ are concentration of reactants, and $a,b,c,andd$ are stoichiometric coefficients.
