Questions
The root mean square (rms) speed of oxygen molecules (O2) at a certain absolute temperature is v. If the temperature is doubled and oxygen gas dissociates into atomic oxygen, rms speed would be
detailed solution
Correct option is C
v=3RTM α TMTemperature is doubled. When gas dissociates, molecular weight halves. So, velocity doubles.Talk to our academic expert!
