We are being asked to calculate Kfor the given reaction, where its Kp is given.

SnO2(s) + 2 CO(g)   Sn(s) + 2 CO2(g),       Kp = 0.025 at 500 ºC


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:
