You Wish to Measure the Extent of Reaction by Monitoring $\degree$

question 83

Multiple Choice

You wish to measure the extent of reaction by monitoring pressure changes.Suppose 1.000 atm of tungsten hexafluoride gas at 400.00 $\degree$ C in a 20.0 L deposition chamber partially decomposes to form tungsten metal and fluorine gas.The products of the reaction at this point are cooled to 25.00 $\degree$ C.The resulting pressure, which is due to the sum of the pressures of F₂ and leftover WF₆, is 1.028 atm.What is the pressure due to the unreacted WF₆?
WF6 (g) $\rightarrow$ W(s) + 3 F₂ (g)

• A)0.3395 atm
• B)0.6605 atm
• C)0.9830 atm
• D)0.1230 atm
• E)0.1504 atm
