Match Column I with Column II — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Translational KE per mole $= \frac{3}{2}RT$. Values are proportional to T: H₂ (300), CH₄ (400), O₂ (900), He (600). Maximum is O₂ (C $\rightarrow$ P), minimum is H₂ (A $\rightarrow$ R). Translational KE per gram $= \frac{3}{2}RT/M$. Values are proportional to $T/M$: H₂ (300/2 = 150), CH₄ (400/16 = 25), O₂ (900/32 = 28.1), He (600/4 = 150). Maximum is H₂ and He (A $\rightarrow$ Q, D $\rightarrow$ Q). Minimum is CH₄ (B $\rightarrow$ S). Therefore, correct answer is 1-B, 1-C, 2-D, 3-A, 4-B.
