Calculate Kp for the reaction?

Question

Calculate Kp for the reaction


NO(g) + O3(g) → NO2(g) + O2(g)


under the following conditions:


T = 298 K



Pressure of NO = 1.62 x 10-5 atm
Pressure of O3 = 1.10 x 10-5 atm



Pressure of NO2 = 2.70 x 10-6 atm
Pressure of O2 = 2.25 x 10-2 atm

Answer 1

At this point in your chemistry course, you should have no problem writing the expression for an equilibrium constant, K, from the balanced chemical equation. Once you have done that, just plug in the pressures of the gases at equilibruim and calculate K.
