K, Kc and Kp: Chemical Engineering WorkWatch
I am aware that you can write: Rate = Kc * Conc(A)^a * Conc(B)^b
I also know how to calculate Kc and Kp and that they can be related to each other through the Ideal Gas Equation.
What I am unclear of is whether I can use Kp in the above equation and how that would work. for example, would the following be true?
Rate = Kp * Partial Pressure(A)^a * Partial Pressure(B)^b
Lastly, how does K link to Kp and Kc?
With the Arrhenius Equation we can say: K = A*exp(-Ea/RT)
Would this be equally valid for Kp and Kc?
Thank you for your help and sorry if my thoughts are a little jumbled!

They are quite different. You cannot put Kc or Kp into the rate equation.
