In a kinetic study of the reaction
2NO(g) + O2 --> 2NO2(g)

the following data were obtained fro the initial rates if disapperance of NO:
Initial concentraition
NO O2 Inital Rate NO
exp 1. 0.0125M 0.0253M 0.0281 M/s
exp 2. 0.0250M 0.0253M 0.0112 M/s
exp 3. 0.0125M 0.0506M 0.0561 M/s

Obtain the rate law. What is the value of the rate constant?

    The equilibrium constant for the reaction 2NO(g) + O2(g) 2NO2(g) is Kp=1.48x10^4 at 184C. Calculate Kp for 2NO2(g) 2NO(g) + O2(g). I know the equation is Kp=Kc(RT)x Delta n Kp is what we're solving for Kc= I can't seem to find.
