Find the appropiate equilibrium constant (Kp) for the reaction below under the following conditions.
1/2SnO2 (s) + H2(g) <--> H2O(g) + 1/2 Sn(s)
a)At 650 degrees celsius the equilibrium steam - H2 mixture was 38 % H2 by volume.
b)At 800 degrees celsius the equilibrium steam- H2 mixture was 22% H2 by volume.
c)Would you run this reaction at high or low temperature for the most efficient reduction of Tin (IV)
