Initially the root mean square velocity (rms) of $N_{2}$ molecules at certain temperature is u . If this temperature is doubled and all the nitrogen molecules dissociate into nitrogen atoms, then the new rms velocity will be :

Options:

Answer:

Solution:

$u = \frac{3 RT}{28}$

$u^{'} = \frac{3 R \times 2 T \times 2}{14 \times 2} = 2 \times \frac{3 RT}{28} = 2 u$
