Combustion Partial Pressure

  1. Sep 11, 2009 #1
    1. The problem statement, all variables and given/known data

    We discussed the fact that the formation of some trace gases is thermodynamically unfavorable at low temperature, but more favorable at elevated temperatures. Using the values for delta G and delta H in the notes, calculate the equilibrium partial pressure of NO2 during combustion at at 1 atm and T = 1600 K.

    3. The attempt at a solution
    Just getting stuck on what the partial pressure of [N] and [O2] are.

    Calculate K for the reaction, assume you start with just NO2, then pressures of other gasses can be calculated from the reaction stoichiometry.

    The wording seems to be unclear.
