Select correct statement:

Options

A. kinetic energy of `O_(2)` is zero at `O^(@)C`
B. rms velocity of `O_(2)` at `27^(@)C` is `sqrt((3xx8.314xx300)/(32))m//s^(2)`
C. distribution of molecules is very small when `u to 0` or `u to oo`
D. all the statements are correct

Answer

C

Explanation

Kinetic energy cannot be zero at `0^(@)C` for all gases.
`(r_(O_(2)))_(27^(@)C)=sqrt((3xx8.314xx300)/(32xx10^(-3)))m//s`
