Question

Please help!
I can't seem to set this up right

At any given temperature
2NO(g) + O2(g) <-> 2NO2 kp=1X10^4
2NO2(g) <-> N2O4 kp=1X10^-1

Find the kp
2NO(g) < -> O2(g) + N2(g) kp=?

Answer 1

I don't believe this can be done with the data listed. I think at least one equation is missing.

Answer 2

No other equations are provided however the question goes on to ask if enough N2O4(g) is placed in a container to achieve 1.00 atm of pressure at this temperature, predict what the final pressures of each of the gasses will be.
