Mass Transfer - Engineering

Q1:

Raoult's law is applicable to the

A ideal solutions

B real solutions

C mixture of water and alcohol

D non-ideal gases

ANS:A - ideal solutions

Raoult's law is primarily applicable to ideal solutions, which are mixtures where the interactions between the molecules of the different components and the solvent molecules are assumed to be the same as those between the solvent molecules themselves. In such ideal solutions:

  • The vapor pressure of each component is directly proportional to its mole fraction in the solution.
  • The total vapor pressure of the solution is the sum of the vapor pressures of the individual components.
However, it's important to note that Raoult's law is an idealized model and may not perfectly describe real-world solutions, especially those involving significant deviations from ideal behavior.
