In the following reaction
N2O4(g) <-----> 2 NO2(g),
equilibrium is reached at a temperature at which partial pressure of NO2 P_NO2 = 3(P(of)N2O4)^1/2.
What must be the value of equilibrium constant Kp at this temperature?
It finds out the equilibrium constant Kp of the reaction given the partial pressures.
