Answer» ΔTb=3×0.1×0.512 Explanation:“The partial vapour PRESSURE of any component in the SOLUTION is directly proportional to its mole fraction”. PA = KXA Where, PA = Partial vapour pressure of A XA = Mole fraction of A in solution For pure liquids XA = 1 Then K = P0A Where P0A is the vapour pressure of component A in pure state Hence, PA = XAP0A Similarly for component B , PB = XBP0A Roults law is applied for a solution of liquid in liquids
