At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Kc, which is a mathematical expression based on the chemical equation. For example, in the reaction aA+bB⇌cC+dD where a, b, c, & d are the stoichiometric coefficients, the equilibrium constant is Kc=[C]c[D]d[A]a[B]b & where [A][A], [B][B], [C][C], and [D][D] are the equilibrium concentrations. If the reaction is not at equilibrium, the quantity can still be calculated, but it is called the reaction quotient, Qc, instead of the equilibrium constant, Kc.Qc=[C]tc[D]td[A]ta[B]tb where each concentration is measured at some arbitrary time t. Part A A mixture initially contains AA, BB, and CC in the following concentrations: [A]= 0.700 M, [B]= 1.40 M, & [C]= 0.550 M.
