We are being asked to calculate Kc for the given reaction, where its Kp is given.
SnO2(s) + 2 CO(g) ⇌ Sn(s) + 2CO2(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:
For the reaction SnO2(s) + 2 CO(g) <=> Sn(s) + 2CO2(g), Kp = 0.025 at 500 °C. The value of Kc is:
