Question

Match each quantity of a van der Waals gas in Column I with the expressions in Column II that give it (a Column I entry may match more than one Column II entry):

Column I (Quantity)	Column II (Expression)
(P) Boyle temperature	(1) $a / (R b)$
(Q) critical temperature	(2) $8 a / (27 R b)$
(R) critical pressure	(3) $a / (27 b^{2})$
(S) critical volume	(4) 3b
	(5) $(27/8) T_{c}$
	(6) $3 R T_{c} / (8 P_{c})$

Choose the option with the correct matching:

(P) T B ​ = a / ( R b ) (1) and also T B ​ = ( 27/8 ) T c ​ (5). (Q) T c ​ = 8 a / ( 27 R b ) (2). (R) P c ​ = a / ( 27 b 2 ) (3). (S) V c ​ = 3 b (4); using Z c ​ = 3/8 , V c ​ = 3 R T c ​ / ( 8 P c ​ ) (6). Correct matching: P to 1,5; Q to 2; R to 3; S to 4,6. Answer: (D).
