Best ResponseYou've already chosen the best response.0adding a substance will lower vapor pressure. so I think A. is out immediately

Best ResponseYou've already chosen the best response.0It looks like this is exactly what you need: http://chemwiki.ucdavis.edu/Physical_Chemistry/Physical_Properties_of_Matter/Solutions_and_Mixtures/Ideal_Solutions/Changes_In_Vapor_Pressure%2C_Raoult's_Law#Nonvolatile_solutes I haven't seen this sort of thing in a while so I'm trying to catch up to understanding this problem too right now, so let's see if we can use this example to get the same answer for your question.

Best ResponseYou've already chosen the best response.1the change in vapor pressure will be proportional to the mole fraction of the solute in the solution, if I remember it properly
