Problem

At a given temperature the following equilibria are established. 1) CO(g)+

\tfrac{1}{2}\,O₂

(g) ⇌ CO₂(g);

K_1 = 1.0\times10^{5}

2) CO₂(g)+H₂(g) ⇌ CO(g)+H₂O(g);

K_2 = 1.6\times10^{-1}

Determine the value of the equilibrium constant for the reaction H₂(g)+

\tfrac{1}{2}\,O₂

(g) ⇌ H₂O(g). a)

6.3\times10^{5}

6.3\times10^{4}

1.6\times10^{4}

1.6\times10^{3}
