Words and meanings to learn
equilibrium
a general state where the concentrations of reactants and products remain constant over time
dynamic equilibrium
occurs in a reversible reaction when the forward and backward reactions happen at the same rate, and the concentrations of reactants and products stay constant, but particles are still reacting
Le Chatelier’s principle
if a change is made to a system at equilibrium, the position of equilibrium shifts to oppose the change and restore balance
pressure
the force exerted by gas particles colliding with container walls; changing pressure affects equilibrium in reactions involving gases
concentration
the amount of a substance in a certain volume; increasing concentration can affect the position of equilibrium
