Calculate the equilibrium constant for the chemical reaction, given the equilibrium concentrations of the reactants and products in the table. $2\mathrm{AB}(aq)+4\mathrm{CD}(aq)?2\mathrm{AD}(\mathrm{aq})+2\mathrm{BD}(\mathrm{aq})+4\mathrm{C}(\mathrm{aq})$ When determining the equilibriam concentrations for the reaction $\mathrm{AB}(\mathrm{g})?\mathrm{A}(\mathrm{g})+\mathrm{B}(\mathrm{g})K_e=\frac{[\mathrm{A}][\mathrm{B}]}{[\mathrm{AB}]}$ a simplifying assumption can be used under certain conditions to avoid solving a quadratic equation. $K_c=\frac{x^2}{[AB]?x}?\frac{x^2}{[AB]}$ Classify each situation by whether the simplifying assumption can be used or whether the quadratic formisla is toquired. Balance the equation. equat incortect Write the reaction-quotient expression, $Q_6$, for this reaction.
