A solution composed of an equal number of moles of acetone and chloroform has a vapor pressure of 250 torr at 35 degrees celsius. (a) what would be the vapor pressure of the solution if it exhibited ideal behavior? (b) Use the existence of hydrogen bonds between acetone and chloroform molecules to explain the deviation from ideal behavior.
