Question

What will be the effect on the root mean square velocity of oxygen molecules if the temperature is doubled and the oxygen molecule dissociates into atomic oxygen?

पर्याय

• The velocity of atomic oxygen remains the same.

• The velocity of atomic oxygen doubles.

• The velocity of atomic oxygen becomes half.

• The velocity of atomic oxygen becomes four times.

Answer 1

The velocity of atomic oxygen doubles.

Explanation:

`ν_{rms} = sqrt((3RT)/M_0)`; `ν_{rms} ∝ sqrt(T/M_0)`

as T becomes double and M₀ becomes half.

So, ν_rms will become `sqrt4` times i.e. 2 times.
