Pick out the wrong statement.
(A) With decrease in feed temperature, the number of plates required for
binary distillation decreases for a given ‘L/V’ ratio
(B) The extraction per unit of total height for a short packed column is more
effective than for a tall column, in case of liquid-liquid extraction
(C) Natural draft cooling towers are made of ferroconcrete and its crosssection is wider at the bottom
(D) Vander wall adsorption is also called chemisorption
