Questions 14-17 refer to the following information.
Substance | Lewis Diagram | Boiling Point
CH3OH | [Lewis structure of methanol] | 338 K
C2H5OH | [Lewis structure of ethanol] | 351 K
Equimolar samples of CH3OH(l) and C2H5OH(l) are placed in separate, previously evacuated, rigid 2.0 L vessels. Each vessel is attached to a pressure gauge, and the temperatures are kept at 300 K. In both vessels, liquid is observed to remain present at the bottom of the container at all times. The change in pressure inside the vessel containing CH3OH(l) is shown below.
The value of Kp for the evaporation of CH3OH(l) at 300 K is closest to
A.
0.04
B.โ Correct
0.2
C.
5
D.
30
