Which of the following condition is correct for reverse osmosis? [ C = . Concentration of solution in mol L ⁻¹ ; T = Temperature in Kelvin scale; n = no of moles of solute]

Options

  1. AP _ ext = CRT
  2. BP _ ext > CRT
  3. CP _ ext < CRT
  4. DP _ ext > nRT

Correct answer

B. P _ ext > CRT

Step-by-step solution

In reverse osmosis, the solvent molecules moves from high concentration solution to low concentration solution through a semipermeable membrane when the external pressure exceeds the osmotic pressure.
