Based on a Ke value of 0.210 and the given data table, what are the equilibrium concentrations of XY, X, and Y, respectively? Express the molar concentrations numerically. Consider mixture B, which will cause the net reaction to proceed forward. net> Concentration (M) [XY] [X] + [Y] initial: 0.500 0.100 0.100 change: +x equilibrium: 0.500 x 0.100 + x 0.100 + x The change in concentration, x, is negative for the reactants because they are consumed and positive for the products because they are produced.
