Chapter 15, Problem 54E

Interpretation Introduction

Interpretation:

For the given concentration of reactants and products, the value of equilibrium constant at a certain temperature is to be calculated.

Concept Introduction:

The equilibrium constant is the ratio of concentrations of products to that of reactants each raised to the power of their stoichiometric coefficients. Consider the general chemical reaction as follows: $\text{aA}+\text{bB}\rightleftharpoons \text{cC}+\text{dD}$.

The expression for the equilibrium constant for the above reaction is 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, the reactants are $\text{A}$ and $\text{B}$, the products are $\text{C and D}$, and the stoichiometric coefficients are $a,b,c,andd$.
