Raoult's law gives the vapor pressure of an ideal solution of two components at a constant temperature.

Use the dropdown menus to select the components in your solution. Use the sliders to specify the number of moles of each component. Component 1 is represented by the red cylinder and component 2 by the blue cylinder.

The plot illustrates Raoult's law, with vapor pressure in kPa on the

y

axis and the mole fraction on the

x

axis. The red and blue lines represent the partial pressures of the components, while the green line is the total vapor pressure.
