Nitrogen monoxide reacts with oxygen to give nitrogen dioxide:

(a) Place the three gases in order of increasing rms speed at 298 K.
(b) If you mix NO and O₂ in the correct stoichiometric ratio and NO has a partial pressure of 150 mm Hg, what is the partial pressure of O₂?
(c) After reaction between NO and O₂ is complete, what is the pressure of NO₂ if the NO originally had a pressure of 150 mm Hg and O₂ was added in the correct stoichiometric amount?
