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. The reaction quotient Q for : N_(2(g)) + 3H_(2(g)) harr 2NH_(3(g)) is given by Q = ([NH_3]^2)/([N_2][H_2]^3). lhe reaction will proceed in backward direction, when :
