For gaseous state, if most probable speed is denoated by `C^(**),` average speed by C and mean square speed by `barC,` then for a large number of molecules the ratios of these speeds are:

Options

A. `C^(**) : bar(C ) = 1.225 : 1.128 : 1`
B. `C^(**) : bar(C ) : C = 1.128 : 1.225 : 1`
C. `C^(**) : bar(C ) : C = 1: 1.28 : 1.225`
D. `C^(**) : bar(C ) : C = 1 : 1.225 : 1.128`

Answer

C

Explanation

`V_(rm s) = sqrt((3RT)/(M)) V_(ave) = sqrt((8RT)/(pi M)) , V_(m p) = sqrt((2RT)/(M))`
