... Increase in the concentration of sulfur dioxide: The equilibrium shifts right to use up the extra SO2, producing more sulfur trioxide and using up some oxygen. Decreasing the partial pressure of sulfur trioxide: This is equivalent to decreasing the concentration of sulfur trioxide. The equilibrium w ...

... Stability of a phase (or mineral) is partly related to its internal energy (here “E”), which strives to be as low as possible under the external conditions. Metastability exists in a phase when its energy is higher than P-T conditions indicate it should be. (1) Activation Energy is the energy ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
