The equilibrium constant (K_(C)) for the reaction HA +B hArr BH^(+) + A is 100. If the rate constant for the forward reaction is 10^(5) , rate constant for the reverse reaction is

Mass action ratio or reaction quotient Q for a reaction can be calculated using the law of mass action A(g)+B(g) harr C(g) + D(g) Q=([C][D])/([A][B]) . The value of Q decides whether the reaction is at equilibrium or not. At equilibrium, Q = K. For non equilibrium process, Q ne K . When Q gt K , reaction will favour backward direction and when Q lt K , it will favour forward direction. For the reaction : 2A + B harr 3C at 298 K, K_c = 49 A 3L vessel contains 2,1 and 3 moles of A, B and C respectively. The reaction at the same temperature:
