    Help with Chemistry Question
    Can anyone help me with this question? Need to know how to do it for Chemistry exam.

    A mixture of NO, O2 and N2 gases are allowed to reach equilibrium at 1200
    oC in a sealed vessel.
    N2 (g) + O2 (g) 2 NO (g)
    The concentrations measured at equilibrium are 1.54 x 10
    -2 M N2, 4.08 x 10
    -3 M O2 and
    2.64 x 10
    -5 M NO.
    (i) Determine a value for the equilibrium constant Kc. (3 marks)
    (ii) Write an expression for Kp. (2 marks)
    (iii) Would the numerical values of Kc and Kp be equal for this reaction? Explain. (2.5 marks)
    (iv) Would the addition of oxygen favour the forward or reverse reaction? (1 mark)
    (v) What effect, if any, would the addition of oxygen have on the value of the equilibrium
    constant? (1 mark)

    Might be more appropriate in the chemistry section of science board.
