Chapter 15, Problem 94E

Interpretation Introduction

Interpretation:

The grams of $\text{NOBr}$ in equilibriummixture, is to be calculated.

Concept Introduction:

The system is said to be in equilibrium when the rate of forwardingreaction becomes equal to the rate ofbackwardreaction.

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

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