We are being asked to calculate Kp for the following reaction where its Kc is given.

H2(g) + CO2(g) ↔ H2O(g) + CO(g)


When dealing with equilibrium:

Kc → equilibrium units are in molarity 
Kp → equilibrium units in terms of pressure


Kp and Kc are related to one another by the following equation below: 

Kp=KcRTn
