Correct Answer is : Kp is greater than Kc

{\K}_{ {\p}} is greater than {\K}_{ {\c}}

{\K}_{ {\p}} is less than {\K}_{ {\c}}

Whether {\K}_{ {\p}} is greater than, less than or equal to {\K}_{ {\c}} depends upon the total gas pressure

For the reaction 2NO2(g)⇋2‌NO(g)+O2(g),(Kc=1.8×10−6. at 184∘C)(R=0.0831‌kJ‌/(mol.K))
When Kp and Kc are compared at 184∘C, it is found that

[AIEEE 2005]

Kp is greater than Kc
Kp is less than Kc
Kp=Kc
Whether Kp is greater than, less than or equal to Kc depends upon the total gas pressure
