For the reaction 2NO2 (g) $$\leftrightharpoons$$ 2NO (g) + O2 (g), (Kc = 1.8 $$\times$$ 10-6 at 184oC) (R = 0.0831 kJ/(mol. K))
When Kp and Kc are compared at 184oC , it is found that :
A
Kp is greater than Kc
B
Kp is less than Kc
C
Kp = Kc
D
Whether Kp is greater than, less than or equal to Kc depends upon the total gas pressure
