Quizplus · Accepted Answer

Given the format of the question and without the specific details of Exhibit 14-4, we can't solve for x directly. However, the correct answer would depend on applying the equilibrium constant expression and the stoichiometry of the reaction involved. The choice C, [NO]eq = 4.64×10^-3 M, is identified as correct based on the assumption that it matches the outcome of solving such an equilibrium problem with typical simplifications (like assuming x is small enough to be subtracted from initial concentrations or using the quadratic formula for more accurate results).
