The generic reaction has the following rate laws: 2A=B forward reaction : rate = kf[A]^2 reverse reaction : rate = kr[B] where kf is the rate constant for the forward reaction and k1 is the rate constant for the reverse reaction. At equilibrium, The two rates are equal and so kf[A]^2 = kr[B]. The equilibrium constant for a reaction is related by the law...
