What will be the effect on the root mean square velocity of oxygen molecules if the temperature is doubled and oxygen molecule dissociates into atomic oxygen?
- A The velocity of atomic oxygen remains same
- B The velocity of atomic oxygen doubles
- C The velocity of atomic oxygen becomes half
- D The velocity of atomic oxygen becomes four times
Answer & Solution
Correct Answer
(B) The velocity of atomic oxygen doubles
Step-by-step Solution
Detailed explanation
\(V _{ mms }=\sqrt{\frac{3 RT }{ M }}\) \(T \rightarrow 2 T\) \(M \rightarrow \frac{ M }{2}\) \(V _{ rms } \propto \sqrt{\frac{ T }{ M }}\)…
