i have recently got a question in an assignment, which was somewhat like this
what would be the shape of curve obtained in a graph between vapour pressure & temperature of a binary solution in a closed vessel
generally we do all the experiments regarding vapour pressure in a closed vessel, so the volume must remain constant and from the formula PV=nRT, the number of moles remains constant in a binary solution, as volume is remaining constant we get the equation as Y=mX, which is a straight line passing through the origin,
but the answer was a sigmoid curve, how did we get that, can i get an elaborate answer for this quiery.
