If you calculate Kp and Kc of the same chemical equation with the same conditions, would the values of Kp and Kc be the same? There is the logic that because both Kp and Kc are simply rations of products/reactants, they would be the same. If they are not the same, why not?

They are the same in some cases and different in others. If you look at table 11.2 on page 428 in the sixth edition of the book, some values of Kc and Kp are the same and some are different even thought its the same chemical reaction.

It varies based on reaction. You know whether Kp and Kc are the same based on your calculations!
