Which of the following condition is correct for reverse osmosis?
$\left[\mathrm{C}=\right.$ Concentration of solution in $\mathrm{mol} \mathrm{L}^{-1} ; \mathrm{T}=$ Temperature in Kelvin scale; $\mathrm{n}=$ no of moles of solute]
$\mathrm{P}_{\mathrm{ext}}=\mathrm{CRT}$
$\mathrm{P}_{\mathrm{ext}}>\mathrm{CRT}$
$\mathrm{P}_{\mathrm{ext}} < \mathrm{CRT}$
$\mathrm{P}_{\mathrm{ext}}>\mathrm{nRT}$
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.
