Key terms
Dynamic Equilibrium
A state in a closed system where the rates of the forward and reverse reactions are equal, leading to constant concentrations of reactants and products.
Le Chatelier's Principle
A principle stating that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.
Equilibrium
A state in a reversible reaction where the rates of the forward and reverse reactions are equal.
Concentration
The amount of a substance in a given volume, often expressed in mol/dm³.
Dynamic Equilibrium
A state of balance in a reversible reaction where the rate of the forward reaction equals the rate of the backward reaction.
Mole Ratio
The ratio of the amounts of reactants and products in a balanced chemical equation.
Exothermic Reaction
A reaction that releases heat to the surroundings, resulting in an increase in temperature of the surroundings.
Dynamic Equilibrium
A state in which the rates of the forward and reverse reactions are equal, leading to constant concentrations of reactants and products.
Catalyst
A substance that increases the rate of a chemical reaction without being consumed in the process.
Equilibrium constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a given reaction at a specific temperature.
Equilibrium constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
Homogeneous equilibrium
An equilibrium in which all reactants and products are in the same phase, typically gaseous or aqueous.
Equilibrium
A state in a reversible reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
Dynamic equilibrium
A condition in which the concentrations of reactants and products remain constant over time, although both the forward and reverse reactions continue to occur.
Equilibrium constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a reversible reaction.
Le Chatelier's principle
A principle stating that if an external change is applied to a system at equilibrium, the system adjusts to minimize that change.
Equilibrium constant (Kc)
A numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a given reaction at a specific temperature.
Le Chatelier's principle
A principle stating that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
Equilibrium
A state in a chemical reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
Le Chatelier's Principle
A principle stating that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
