Question
The vapor pressure of liquid carbon tetrachloride, CCI4, is 100. mm Hg at 296 K. A 0.261 g sample of
liquid CCI4 is placed in a closed, evacuated 400. mL container at a temperature of 296 K.
Assuming that the temperature remains constant, will all of the liquid evaporate?
What will the pressure in the container be when equilibrium is reached?
mm Hg

A sample of 3.73 mol of argon is confined at low pressure in a volume at a temperature of 61 C. Describe
quantitatively the effects of each of the following changes on the pressure, the average kinetic energy per
molecule in the gas, and the root-mean-square speed.
(a) The temperature is increased to 177 °C.
(b) The volume is tripled.
(c) The amount of argon is decreased to 1.96 mol.
Give each answer as a decimal factor of the form: new value = factor old value. A factor of 1 means no
change.
