7.6 Properties of the Equilibrium Constant
At a given temperature, the equilibrium constants for the following two reactions are known:
\(\text{2 NO(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{NO}_2\text{(g)}\) \quad \(K_1 = 2.0 \times 10^4\)
\(\text{N}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{NO(g)}\) \quad \(K_2 = 5.0 \times 10^{-2}\)
Based on this information, what is the value of the equilibrium constant, \(K_c\), for the reaction \(\text{2 NO}_2\text{(g)} \rightleftharpoons \text{N}_2\text{(g)} + 2\text{O}_2\text{(g)}\) at the same temperature?
\(\text{2 NO(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{NO}_2\text{(g)}\) \quad \(K_1 = 2.0 \times 10^4\)
\(\text{N}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{NO(g)}\) \quad \(K_2 = 5.0 \times 10^{-2}\)
Based on this information, what is the value of the equilibrium constant, \(K_c\), for the reaction \(\text{2 NO}_2\text{(g)} \rightleftharpoons \text{N}_2\text{(g)} + 2\text{O}_2\text{(g)}\) at the same temperature?
