Negative deviation from raoult's law example

WebNov 15, 2024 · Examples of negative Deviation. If the solute A-A bond and solvent B-B is weaker than A-B bond i.e. solute and solvent are tightly bound to each other as they are to themselves, then the solution will show a negative deviation from Raoult's law because the solvent molecules will not find it easier to escape from solution into the gas phase. WebApr 11, 2024 · Raoult's law [Click Here for Sample Questions] According to Raoult's law, “the vapour pressure of any solution containing a non-volatile solute in a volatile solvent is proportional to the mole fraction of the solvent in the solution.” Raoult's law was first given by French chemist François-Marie Raoult in the year 1887.

WebApr 3, 2024 · Example: A solution of water and ethanol. Negative deviation from Raoult’s: In this type of deviation the partial pressure of each component of solution is less than that expected from Raoult’s law, i.e., P A < P° A x A & P B < P° B x B. Example: A solution of acetone and chloroform. WebAccording to Raoult’s law, p A = x A x p A 0 = 5/15 x 64 = 21.33 torr p B = x B x p B 0 = 10/15 x 76 = 50.67 torr Therefore, pressure expected by Raoult’s law = 21.33 + 50.67 = 72 torr. Thus, observed pressure (70 torr) is less than the expected value. Hence, the solution shows negative deviation.
