Consider the gas-phase reaction represented below, for which \(K_c = 5.0 \times 10^{10}\) at \(298\text{ K}\):

\[2\text{NO(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{NO}_2\text{(g)}\]

Which of the following statements best describes the composition of the mixture at equilibrium at \(298\text{ K}\) and provides a correct justification?
