A gas mixture consists of molecules of type 1,2 and 3, with molar masses `m_(1) gt m_(2) gt m_(3).V_(rms) " and "overset(-)(K)` are the r.m.s. speed and average kinetic energy of the gases. Which of the following is true-

A

`(V_"rms")_1lt(V_"rms")_2lt(V_"rms")_3 and (barK)_1=(barK)_2=(barK)_3`

B

`(V_"rms")_1=(V_"rms")_2=(V_"rms")_3 and (barK)_1=(barK)_2gt(barK)_3`

C

`(V_"rms")_1gt(V_"rms")_2gt(V_"rms")_3 and (barK)_1lt(barK)_2gt(barK)_3`

D

`(V_"rms")_1gt(V_"rms")_2gt(V_"rms")_3 and (barK)_1lt(barK)_2lt(barK)_3`

Text Solution

Verified by Experts

The correct Answer is:

A

Since, temperature of all gas is same, hence KE is same.
