Q

What is roults law?

A

PA = XAPºA

PA = vapor pressure when solutes present

XA = mole fraction of solvent A

PºA = Vapor pressure of A in pure state

Q

When solutes are in a solution, the evaporation is blocked by solutes but it doesn’t do anything to condensation. What does this do cause?

A

Causes a decrease in vapor pressure
