Solution
The correct option is B Atmolysis
A process for separating gases or vapors of different molecular weights by transmission through a porous substance is called atmolysis.
The exchange of bonds between two reacting chemical species is Metathesis method.
Ostwald and Walker's Dynamic Method (Gas Saturation Method): In this method, the relative lowering of vapor pressure can be calculated in an easy simple way Procedure.
A process by which a solvent passes through a porous membrane in the direction opposite to that for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure.
