Le Chatelier’s Principle: The principle that states if a system at equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change.
Reaction Quotient (Q): A measure of the relative amounts of products and reactants present during a reaction at a particular point in time.
Chemical Equilibrium: The state in which both reactants and products are present in concentrations which have no further tendency to change with time.
