Chemical Equilibrium

LT: I will be able to explain chemical equilibrium.
I will do this by:
Use Le Chatelier’s Principle to explain how a change in chemicals, temperature or pressure affect a reaction at equilibrium.

Define a reversible reaction.

Identify a reversible reaction.


A reaction where the reactants form products, which react together to give the reactants back.A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B.


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 principle that if a system in chemical equilibrium is subjected to a disturbance it tends to change in a way that opposes this disturbance.A change in temperature, increases the pressure, on the system increases. This causes a change in equilibrium. Reactants decrease and products increase.
