The partial pressures of methane and ethane in the natural gas sample have to be calculated. The total mass of Water produced by the complete combustion of methane and ethane in the natural gas sample has to be determined. Concept Introduction: In a mixture of gaseous substances, the total pressure of the system is equal to the sum of the partial pressure of the each gaseous substance. Thus, the pressure contributed by the individual gaseous substance to the total pressure is known as the partial pressure of that gaseous substance. The partial pressure of a gas depends upon its mole fraction. Mole fraction of a gaseous component is nothing but the number of moles of that particular gaseous substance present in a system containing mixture of gaseous substances. Let us assume a system contains a mixture of two different gases A and B. Let ‘N’ be the total number of moles of gases present in the mixture. Then, Mole fraction of gas A is, X A = number of moles of A Total number of moles Mole fraction of gas B is, X B = number of moles of B Total number of moles Using the number of moles and mole fraction of the reactants and products, the amount of product obtained can be determined.

Chapter 5, Problem 174IP

Interpretation Introduction

Interpretation:

The partial pressures of methane and ethane in the natural gas sample have to be calculated.

The total mass of Water produced by the complete combustion of methane and ethane in the natural gas sample has to be determined.

Concept Introduction:

In a mixture of gaseous substances, the total pressure of the system is equal to the sum of the partial pressure of the each gaseous substance.

Thus, the pressure contributed by the individual gaseous substance to the total pressure is known as the partial pressure of that gaseous substance.

The partial pressure of a gas depends upon its mole fraction. Mole fraction of a gaseous component is nothing but the number of moles of that particular gaseous substance present in a system containing mixture of gaseous substances.

Let us assume a system contains a mixture of two different gases A and B. Let ‘N’ be the total number of moles of gases present in the mixture. Then,

Mole fraction of gas A is, XA= number of moles of ATotal number of moles

Mole fraction of gas B is, XB= number of moles of BTotal number of moles

Using the number of moles and mole fraction of the reactants and products, the amount of product obtained can be determined.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments. This especially applies to the reactions in…
