Because the calorimeter prevents the gain or loss of heat from its surroundings, the heat released by the reaction, qrxn, equals that gained by the solution, qsoln. Thus, securon medicationWebAs 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 and closer to Kc until, at equilibrium, Qc equals Kc.
