Words and meanings to learn
concentration
the amount of a substance in a certain volume; increasing concentration can affect the position of equilibrium
pressure
the force exerted by gas particles colliding with container walls; changing pressure affects equilibrium in reactions involving gases
equilibrium
a general state where the concentrations of reactants and products remain constant over time
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
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
