Study Notes
Chemical Equilibrium
- The state in which both reactants and products are present in concentrations that have no further tendency to change with time is called chemical equilibrium.
- In chemical equilibrium, the forward reaction proceeds at the same rate as the reverse reaction.
- At equilibrium, the reaction rates of the forward and backward reactions are equal, not zero.
