raoult's law vapour pressure diagram

The total vapor pressure, P exerted by the solution is the sum of P A and P B as required by Dalton's law of partial pressures. P = P A + P B or P = P o A c A + P o B c B = P o A (1- c B ) + P o B c B [because c A + c B = 1] = P o A - P o A c B + P o B c B P = (P o B -..

In 1886 the French chemist Francois Marie Raoult carried out a series of experiments to study the vapor pressure of a number of binary solutions containing non-volatile as well as volatile non electrolyte solutes. On the basis of the results of the experiment he stated a h..

Graham's Law of Diffusion - Gases have the tendency to spontaneously intermix and form a homogenous mixture without the help of external agency. This is due to the presence of large amount of empty space between the gas molecules that makes their movement rapid into each other. The gases ..

In this type of deviation, the partial vapor pressure of each component of solution is less than the vapor pressure as expected according to Raoult's law..

Conclusion - Solutions are homogeneous mixtures having great importance in our day to day life. In this chapter we have learnt the various types of solutions, the meaning of vapor pressure, Raoult's Law, Colligative Properties and Abnormal Molecular Mass..

In case of solutions showing positive deviation from Raoult's law, at one of the intermediate compositions, the total vapor pressure is the highest and the boiling point is the lowest. Similarly in case of solutions showing negative deviations from Raoult's h..

Solutions With Negative Deviation - In this type of deviation, the partial vapor pressure of each component of solution is less than the vapor pressure as expected according to Raoult's law..

Solutions are homogeneous mixtures having great importance in our day to day life. In this chapter we have learnt the various types of solutions, the meaning of vapor pressure, Raoult's Law, Colligative Properties and Abnormal Molecular Masse..

Solutions With Positive Deviation - These types of solutions where D H of mixing is >0 and D V of mixing >0 are found to exhibit positive deviation from Raoult's law. Here solute-solute interactions and solvent-solvent interactions are greater than solute - solvent interac..
