Note in passing: I'm not sure about the temperature/ pressure/ composition
 
conditions you're considering, but at room temp & pressure on Earth,
NO in significant concentrations is immediately oxidised to NO2 (or, more
accurately, the equilibrium is well towards NO2). I suspect if there was
enough oxygen around to start forming NO, you'd also start losing it as
NO2.
