2NO + O2 -> 2NO2

200. mL of NO at STP is reacted with 500. mL O2of at STP. Calculate the partial pressure of NO2 after the reaction goes to completion. Assume a constant volume.

  • chemistry -

    Constant volume? Exactly what is the volume...200ml, 500ml, or 700ml. It would be interesting to see how this reaction was accomplished. What was the temperature of the vessel when completed?

  • chemistry -

    Of NO2? it's not given.
    That's all they gave me..
