Beaker A has 1.00 mol of chloroform, CHCl3, at 27C. Beaker B has 1.00 mol of carbon tetrachloride, CCl4, also at 27C. Equal masses of

Beaker A has 1.00 mol of chloroform, CHCl3, at 27ºC. Beaker B has 1.00 mol of carbon tetrachloride, CCl4, also at 27ºC. Equal masses of a nonvolatile, nonreactive solute are added to both beakers. In answering the questions below, the following data may be helpful.

	CHCl3 (A)	CCl4 (B)
Vapor pressure at 278C	0.276 atm	0.164 atm
Boiling point	0.164 atm	76.58C
kb (ºC/m)	3.63	5.03
