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:

1.	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:
Answer» must proceed in forward direction must proceed in backward direction must be in EQUILIBRIUM cannot be predicted Solution :`Q_(C)=([C]^(3))/([A]^(2) XX [B])=((3//3)^(3))/((2//3)^(2) xx (1//3))=(27)/(4) lt K_(C)`
