#5 0.5m BaBr2, 0.5m NaF, 0.5m CO2, 0.5m CH3COOH Which has lowest freezing point, greatest vapor pressure, and arrange by increasing boiling point. I got boiling/freezing points CO2 < CH3COOH < NAF < BaBr2 So greatest would be CO2 But I am confused by CH3COOH and NaF, both have van hoff of 2 so how do we know which boiling point is higher?
