The approach to equilibrium 2 We can analyse this behaviour by thinking of a very simple reaction Forward: A → B Rate of formation of B d[B]/dt = k [A] Reverse: B → A Rate of decomposition of B d[B]/dt= k’ [B] Net rate of formation of B d[B]/dt= k [A]- k’ [B] At equilibrium, it is equal to zero 0= k [A] eq - k’ [B] eq K= k/k’= [B] eq / [A] eq The temperature dependence of equilibrium constant

4 The term relaxation denotes the return of a system to equilibrium. It is used in chemical kinetics to indicate that an externally applied influence has shifted the equilibrium position of a reaction,
