Solution: The following diagram shows the vapor pressure curves of a volatile solvent and a solution of that solvent containing a nonvolatile solute. Which line represents the solution?

Problem

The following diagram shows the vapor pressure curves of a volatile solvent and a solution of that solvent containing a nonvolatile solute.
The x-axis is temperature (degrees C) ranging from 40 to 70 with intervals of 10. The y-axis is pressure in atmospheres with one horizontal dashed line at 1.0 about two thirds of the way up the y-axis. Two parallel curves are plotted (red and blue). Both start at 40 degrees C about one-third of the way up the y-axis, but the red curve is above the blue curve. The red curve crosses 1.0 atmospheres at about 64 degrees C and the blue curve crosses 1.0 at 70 degrees C.

Which line represents the solution?
