1.	Which of the following relation between driving force and unit operation is correct?(a) Crystallization – relative solubility in different solvents(b) Extraction – relative volatilities(c) Absorption – freezing point difference(d) Adsorption – relative adherenceThis question was addressed to me in class test.The question is from Natural Products topic in division Natural Products of Chemical Technology
Answer» The correct option is (d) Adsorption – relative ADHERENCE Easy explanation: The GENERAL driving FORCE for any unit OPERATION is concentration gradient or more precisely chemical potential. The correct option is that adsorption is BASED on relative adherence.
