0:00:00   Introduction to Lecture 6
0:00:26 Derivation of Raoult's law (graph of partial vapour pressure, raoult's law graph, derivation of raoult's law, total vapour pressure, binary solution,)
0:11:11 Quick recap of Dalton's Law, Henry's Law, and Raoult's Law (dalton's law, raoult's law, henry's law, partial pressure, partial pressure of component, Total pressure, )
0:18:56 example on Vapour pressure (Vapour pressure of chloroform and dichloromethane at 298K are 200mmHg and 415mmHg respectively,)
0:29:27 Raoult's law as a special case of Henry's Law (How Raoult's law is a special case of Henry's Law?, relation between henry's law and raoult's law,)
0:32:42 example on Vapour pressure (The Vapour pressure of pure liquids A and B are 450  and 700 mmhg respectively at 350K. find out the composition of the liquid mixture if total vapour pressure is 600 mmHg. also find the composition of the vapour phase.,)
0:36:24 example on Vapour pressure (A solution of A and B with 30 moles percent of A is in equilibrium with its vapour which contain 60 mole percent of A. Assuming that the solution and the vapour behave ideally, calculate the ratio of the vapour pressures of pure A and pure B,)
0:41:22 example on Vapour pressure (Vapour pressure of benzene and toluene in a mixture at 50C are given in mm by P= 179X^b+92 where X^b is the mole fraction of benzene. calculate vapour pressure of pure benzene and toluene at 50C,)
0:43:54 Vapour pressure of solution of solids in liquids (Vapour pressure, partial vapour pressure, vapour pressure of solids in liquids,)
