Chapter 5, Problem 5.98QP
Interpretation Introduction

Interpretation:

The partial pressure of the given O2 and NO2 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.

PV = nRT

  • The pressure exerted by an individual gas in a mixture is known as its partial pressure.
  • Assuming we have a mixture of ideal gases, we can use the ideal gas law to solve problems involving gases in a mixture.
  • Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases:
  • PTotal=Pgas 1+Pgas 2+Pgas 3....
  • χi=PiPtotal

Answer to Problem 5.98QP

The partial pressure of O2 and NO2 was found to be 0.166atmand 0.333atm respectively.

Explanation of Solution

To calculate the initial number of moles of O2 and NO

nNO=PNOVRT=(0.500atm)(4.00L)(0.08206L.atmK.mol)(298K)=0.0817molNOnO2=PO2VRT=(1.00atm)(2.00L)(0.08206L.atmK.mol)(298K)=0.0817molO2

To determine the molar amounts of NO, O2, and NO2after complete reaction.

mol NO = 0 mol (All NO is consumed during reaction)

molNO2=0.0817molNO×2molNO22molNO=0.0817molNO2molO2consumed=0.0817molNO×1molO22molNO=0.0409molO2consumed

molO2remaining=0.0817molO2initial-0.0409molO2consumed=0.0408molO2

To calculate the partial pressure of the O2 and NO2

PO2=nO2RTV=(0.0408mol)(0.08206L.atmK.mol)(298K)(6.00L)=0.166atmPNO2=nNO2RTV=(0.0817mol)(0.08206L.atmK.mol)(298K)(6.00L)=0.333atm

Conclusion

The partial pressure of the given O2 and NO2 was calculated.
