Chemical Equilibrium

Chemical Equilibrium

Chemical Equilibrium. Chapter 14 14.1-14.5. Equilibrium. Equilibrium is a state in which there are no observable changes as time goes by. Chemical equilibrium is achieved when: 1.) the rates of the forward and reverse reactions are equal and

Chemical Equilibrium

Chemical Equilibrium

Chemical Equilibrium. The reversibility of reactions. Equilibrium. Many chemical reactions do not go to completion. Initially, when reactants are present, the forward reaction predominates. As the concentration of reactants increases, the reverse reaction begins to become significant.
