AP Chemistry
7.5 Magnitude of the Equilibrium Constant
At \(298\text{ K}\), nitrogen gas and oxygen gas react to form nitrogen monoxide according to the following equation:
\[\text{N}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\,\text{NO(g)} \quad K_c = 1.0 \times 10^{-30}\]
An equimolar mixture of \(\text{N}_2\text{(g)}\) and \(\text{O}_2\text{(g)}\) is sealed in a rigid container at \(298\text{ K}\) and allowed to reach equilibrium. Which of the following statements best describes the composition of the mixture at equilibrium, and provides the correct justification?
\[\text{N}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\,\text{NO(g)} \quad K_c = 1.0 \times 10^{-30}\]
