At equilibrium, the concentrations of reactants and products do not change. But the forward and reverse reactions have not stopped - they are still going on, and at the same rate as each other.

It is an iridium complex that catalyses the dehydrogenation of a heterocyclic organic compound, and then in the presence of hydrogen changes itself to catalyse the reverse reaction (the ...

close dynamic equilibriumA dynamic equilibrium is one in which the rate of the forward reaction equals the rate of the reverse reaction and the concentrations of the reactants and products remain ...
