JEE · NEET Previous Year Question

$The most probable speed of O_{2} molecules at T (K) is$

Topic: JEE PYQ

Answer: C. Full step-by-step solution below.

A $\frac{RT}{4 π}$
B $\frac{RT}{16 π}$
C $\frac{RT}{16}$
D $\frac{3 RT}{32}$

Correct answer: C

Solution

(c) Most probable speed μ_{mp} = \frac{2 RT}{M} = \frac{2 RT}{32} (M . Mass of O_{2} = 32) = \frac{RT}{16}
