Use the References to access important values if needed for this question The vapor pressure of liquid ethyl acetate, CHCooC2H, is 100 mm Hg at 300 K. A sample of CH,COOC,Hs is placed in a closed, evacuated 565 ml container at a temperature of 300 K. It is found that all of the CH3CooC,Hs is in the vapor phase and that the pressure is 48.0 mm Hg. If the volume of the container is reduced to 397 mL at constant temperature, which of the following statements are correct? Choose all that apply O Only ethyl acetate vapor will be present. No condensation will occur. The pressure in the container will be 100 mm Hg. Some of the vapor initially present will condense. Liquid ethyl acetate will be present. Submit Answer 2 question attempts remainingExplanation / Answer
from boyles law,
P1V1 = P2V2
(48*565) = (p2*397)
p2 = Vapor pressure at reduced volume = 68.31 mmhg
it is less than, reference value.
so that, only ethylacetate vapor will be present.
