Chapter 15, Problem 23PS

Calculate K for the reaction

SnO₂(s) + 2 CO(g) ⇄ Sn(s) + 2 CO₂(g)

given the following information:

$\begin{array}{l}{\text{SnO}}_{\text{2}}{\text{(s) + 2 H}}_{\text{2}}\text{(g) }\rightleftarrows {\text{ Sn(s) + 2 H}}_{\text{2}}\text{O(g)}K\text{ = 8}\text{.12}\\ {\text{H}}_{\text{2}}{\text{(g) + CO}}_{\text{2}}\text{(g) }\rightleftarrows {\text{ H}}_{\text{2}}\text{O(g) + CO(g)}K\text{ = 0}\text{.771}\end{array}$
