JEE Main 2024 — Kinetic Theory of Gases Question with Solution

JEE Main 2024 (29 Jan Shift 2)

Question

N moles of a polyatomic gas(f=6) must be mixed with two moles of a monoatomic gas so that the mixture behaves as a diatomic gas. The value of N is:

Choose an option

Show full solutionCorrect option: C
Correct answer
C4

Step-by-step explanation

The equivalent degree of freedom feq of the mixture is

feq=n1f1+n2f2n1+n2

For diatomic gas feq=5.

⇒5=(n)(6)+(2)(3)n+2

⇒5n+10=6n+6

⇒n=4
