The root mean square speed of oxygen molecules $(O_{2})$ at a certain absolute temperature is v. If the temperature is doubled and the oxygen gas dissociates into atomic oxygen, the rms speed would be

Options:

Answer:

Solution:

$v = \frac{3 RT}{M}$ ; with $T \to 2 T$ and $M \to M /2$ :

$v^{'} = \frac{3 R ( 2 T )}{M /2} = 2 v .$
