WebMay 31, 2016 · As the reaction progresses towards equilibrium, the concentrations of A and B will decrease as more C is formed. If we keep measuring the concentrations of A, B and C, and calculating [C]/ [A] [B] (which we are calling Qc) then we will find that Qc gets closer … WebQ = K Reaction is already at equilibrium. Also, if any reactant or product is missing in the initial mixture, the reaction will shift in the direction forming some of that component. So, let’s see how the reaction quotient is used to determine the equilibrium concentrations.
