Given a K value of 0.43 for the following aqueous equilibrium, suppose sample Z is placed into water such that it's original concentration is 0.033 M. Assume there was zero initial concentration of either A(aq) or B(aq). Once equilibrium has occurred, what will be the equilibrium concentration of Z? 2A(aq) + B(aq) leftrightarrows 2Z(aq) K = 0.43 more than 0.033 M less than 0.033 M 0.033 M exactly there is no way to tell
