Identify the FALSE statement about ideal solution from following.

Options

  1. AIdeal solutions obey Raoult's law over entire range of concentration.
  2. BNo heat is evolved or absorbed when two components forming an ideal solution are mixed.
  3. CVolume of ideal solution is same as sum of volumes of two components taken for mixing.
  4. DThe vapour pressure of ideal solution is either higher or lower than vapour pressure of pure components.

Correct answer

D. The vapour pressure of ideal solution is either higher or lower than vapour pressure of pure components.

Step-by-step solution

The vapour pressure of ideal solution always lies between vapour pressures of pure components.
