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?
