Question 1 of 5

Consider the given reaction that occurs at 1395 K.

$2 \mathrm{H}_{2} \mathrm{O}(g) \rightleftharpoons 2 \mathrm{H}_{2}(g)+\mathrm{O}_{2}(g) \quad K_{1}=2.1 \times 10^{-13}$

$2 \mathrm{CO}_{2}(g) \rightleftharpoons 2 \mathrm{CO}(g)+\mathrm{O}_{2}(g) \quad K_{2}=1.4 \times 10^{-12}$

The equilibrium constant for the reaction, $\mathrm{H}_{2}(g)+\mathrm{CO}_{2}(g) \rightleftharpoons \mathrm{H}_{2} \mathrm{O}(g)+\mathrm{CO}(g)$ at same temperature is
