For a reaction with a positive An value, the relationship between Kp and Kc at a given temperature is:
•Kp > Kc
• An > 1
This is because the An value is the ratio of the product to the reactants. So, if the reaction has a positive An value, then the reaction is favorable and goes in the forward direction. This leads to a higher value for Kp than Kc and a positive A value for the response.
