Significance of Reversing the Reaction Equation: Let us carry out the reaction, A B, by initiating it from A till equilibrium. And it's a dynamic equilibrium, the reaction is still happening, but if a reaction is an equilibrium, the rate of the forward reaction will equal the rate of the reverse reaction, so there'll be no net change in composition. Chemical equilibria are in general dynamic rather than static. Chemical Equilibrium. equilibrium and if the process involves only chemical change, the equilibrium is called chemical equilibrium. direction of spontaneous change. 1 THE CONCEPT OF EQUILIBRIUM AND THE EQUILIBRIUM CONSTANT Many chemical reactions do not go to completion but instead attain a state of chemical equilibrium.
