7.6 Properties of the Equilibrium Constant
The following reactions and their equilibrium constants at \(1000\text{ K}\) are given:
\[\text{CO}(g) + \frac{1}{2}\,\text{O}_2(g) \rightleftharpoons \text{CO}_2(g) \quad K_1 = 1.2 \times 10^5\]
\[\text{C}(s) + \text{CO}_2(g) \rightleftharpoons 2\,\text{CO}(g) \quad K_2 = 2.5 \times 10^{-3}\]
Based on these data, what is the value of the equilibrium constant, \(K\), for the reaction \(\text{C}(s) + \text{O}_2(g) \rightleftharpoons \text{CO}_2(g)\) at \(1000\text{ K}\)?
\[\text{CO}(g) + \frac{1}{2}\,\text{O}_2(g) \rightleftharpoons \text{CO}_2(g) \quad K_1 = 1.2 \times 10^5\]
\[\text{C}(s) + \text{CO}_2(g) \rightleftharpoons 2\,\text{CO}(g) \quad K_2 = 2.5 \times 10^{-3}\]
Based on these data, what is the value of the equilibrium constant, \(K\), for the reaction \(\text{C}(s) + \text{O}_2(g) \rightleftharpoons \text{CO}_2(g)\) at \(1000\text{ K}\)?
