For a reaction, aA+bBhArrcC+dD , the reaction quotient Q=([C]_(0)^(c)[D]_(0)^(d))/([A]_(0)^(a)[B]_(0)^(b)) , where [A]_(0) , [B]_(0) , [C]_(0) , [D]_(0) are initial concentrations. Also K_(c)=([C]^(c)[D]^(d))/([A]^(a)[B]^(b)) where [A] , [B] , [C] , [D] are equilibrium concentrations. The reaction proceeds in forward direction if Q lt K_(c) and in backward direction if Q gt K_(c) .
