Find the appropriate equilibrium constant (Kp) for the reaction below under the following conditions.
1/2 SNO2(s) + H2(g) <--> H2O(g) + 1/2 Sn(s)
a. At 650*C, The equilibrium steam-H2 mixture was 38% H2 by Volume.
b. At 800*C, The equilibrium steam-H2 mixture was 22% H2 by Volume.
c. Would you run this reaction at a high or low temperature for the most efficient reduction of Tin?
