Homework Help: Equillibrium concentrations

  1. Aug 5, 2007 #1
    :rofl: I am having trouble figuring out the equillibrium equation in ppm for the following reaction N2 + O2 = 2NO. With 10 moles of N2 and 1 mole of O2. I am having trouble figuring out how to start this problem. Can anyone give me a hint...it has been years since i tried this.

    Wait, so you want to find the expression for the equilibrium constant in terms of partial pressure?

    I'm sorry, I need to find the equlibrium concentration of NO.
