If `r_(1),r_(2)andr_(3)` represent the most probable speeds of three different gases at the same temperature as shown in figure with molar masses `M_(1),M_(2)andM_(3)` respectively. The correct order of molar masses of these gases is

A

`M_(1)gtM_(3)gtM_(2)`

B

`M_(3)gtM_(2)gtM_(1)`

C

`M_(2)gtM_(1)gtM_(3)`

D

`M_(2)gtM_(3)gtM_(1)`

Text Solution

Verified by Experts

The correct Answer is:
C
In the direction of x-axis `r_(3)` increases and for same tamperature most probable speed
`prop1/(sqrt("molar mass (M)"))`
Thus, `M_(2)gtM_(1)gtM_(3)`.
