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.
