Equilibrium constants for the following reactions at 1200 K are given:

2H2O(g)⇌2H2(g)+O2(g)2H_2O(g) \rightleftharpoons 2H_2(g) + O_2(g); K1=6.4×10−8K_1 = 6.4 \times 10^{-8}
2CO2(g)⇌2CO(g)+O2(g)2CO_2(g) \rightleftharpoons 2CO(g) + O_2(g); K2=1.6×10−6K_2 = 1.6 \times 10^{-6}

The equilibrium constant for the reaction H2(g)+CO2(g)⇌CO(g)+H2O(g)H_2(g) + CO_2(g) \rightleftharpoons CO(g) + H_2O(g) at 1200 K will be
