Question

the following gases has the highest
Value of R.M.S - Velocity at 298 k?
a) CH4 b) co c) cla d-) con​

Answer 1

Answer:

A) CH4

Explanation:

Lesser the molecular mass higher is the RMS velocity.

RMS velocity is inversely proportional to square root of Molar mass

Hope it helps u

Answer 2

Answer:the correct option is (a) CH4

Explanation: Because its molar mass is very less in given gasses and rms is inversely proportional to square root of molar mass
