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

question 44

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 ^$\circ$ 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 ^$\circ$ 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) $\to$ 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

Definitions:

Smell

The sensory perception of odors or scents, detected by the olfactory system in the nose.

Mechanoreceptors

Mechanoreceptors are sensory receptors that respond to mechanical pressure or distortion, involved in sensations such as touch, pressure, and sound.

Excited By

Stimulated or activated by an external source, leading to an increased level of energy or activity.

Pressure

The force exerted per unit area; in fluids, it is often caused by gravity acting upon the fluid's mass.
