Chapter 11, Problem 11.81QP

Interpretation Introduction

Interpretation:

The volume in liters of the ${\text{NO}}_{\text{2}}$ produced has to be calculated.

Concept Introduction:

Ideal gas is the most usually used form of the ideal gas equation, which describes the relationship among the four variables P, V, n, and T.  An ideal gas is a hypothetical sample of gas whose pressure-volume-temperature behavior is predicted accurately by the ideal gas equation.

$\text{PV = nRT}$

The moles of ${\text{CH}}_{\text{4}}$ that reacts, we can calculate the moles of ${\text{CO}}_{\text{2}}$ produced. From the balanced equation, we see that 1 mol ${\text{CH}}_{\text{4}}$ is stoichiometrically equivalent to 1 mol ${\text{CO}}_{\text{2}}$. Once moles of ${\text{CO}}_{\text{2}}$ are determined, we can use the ideal gas equation to calculate the volume of ${\text{CO}}_{\text{2}}$ .
