Question

A container has a mixture of two gases, hydrogen, and oxygen at room temperature. Which one of the following statements is true, if V_H and V_O are the root mean square velocities of hydrogen and oxygen molecules respectively?

विकल्प

• V_H > V_O

• V_H < V_O

• V_O = V_H 

• Data is insufficient

Answer 1

V_H > V_O

Explanation:

`"V"_"H" = sqrt((3"RT")/("M"_"H")) ,"V"_"O" = sqrt((3"RT")/("M"_"O"))`

As T = constant, V_rms ` alpha 1/sqrt"M"_0`

M_H < M_O ⇒ V_H > V_O
