or

boiling point increase, vapor pressure decrease? or vice versa?

    Neither.
    As # solute particles increases, freezing point decreases and vapor pressure decreases.

    As # solute particles increase, vapor pressure gets smaller and boiling point gets larger.

    I like this statement that summarizes it all.
    As the number of solute particles increases, three things happen.
    a. f.p is lowered.
    b. b.p. is raised.
    c. v.p. is lowered.
