Problem

For the reaction, SnO2(s)+2H2(g)⇌Sn(l)+2H2O(g)\text{SnO}_2(s) + 2\text{H}_2(g) \rightleftharpoons \text{Sn}(l) + 2\text{H}_2\text{O}(g) the equilibrium mixture of steam and hydrogen contained 45% and 24% H2\text{H}_2 at 900 K and 1100 K respectively. Calculate KPK_P at both the temperatures. Generally should it be higher or lower temperatures for better reduction of SnO2\text{SnO}_2 ?
