Match Column I with Column II

Column I	Column II
A) He gas at 200 K	P) Maximum translational KE per mol
B) H₂ gas at 300 K	Q) Minimum translational KE per mol
C) N₂ gas at 700 K	R) Maximum translational KE per gram
D) O₂ gas at 400 K	S) Minimum translational KE per gram

TestHub · Accepted Answer

Translational KE per mol = (3/2)RT depends only on T: maximum for N₂ at 700 K (C → P), minimum for He at 200 K (A → Q). Per gram it is (3/2)RT/M ∝ T/M: He: 200/4 = 50; H₂: 300/2 = 150; N₂: 700/28 = 25; O₂: 400/32 = 12.5. Maximum per gram is H₂ (B → R); minimum per gram is O₂ (D → S). Hence A → Q; B → R; C → P; D → S.
