The idea that when a system at equilibrium is stressed, it will react to relieve that stress and return to equilibrium is known as:

• Boyle's Law
• Le Chatelier's Principle
• Charles Law
• Denninger's Law

A chemical reaction is in equilibrium when

• the forward and reverse reaction have stopped.

• the equilibrium constant equals 1.

• the forward and reverse reaction rates are equal.

• no reactants remain

A product is

• the condition of continuous, random movement of particles but no overall change in concentration of materials.

• a measurement of how much solute exists within a certain volume of solvent or solution.

• a substance that forms in a chemical reaction.

• the reaction that forms products from reactants.

A reactant is

• the reaction that forms products from reactants.

• a measurement of how much solute exists within a certain volume of solvent or solution.

• a substance that takes part in and undergoes change in a chemical reaction.

• the condition of continuous, random movement of particles but no overall change in concentration of materials.

Dynamic equilibrium is

• the condition of continuous, random movement of particles but no overall change in concentration of materials.

• the process by which one or more substances change to produce one or more different substances.

• a condition where the reaction is completely halted and there exists no movement between the reactants and the products.

• a substance that takes part in and undergoes change in a chemical reaction.

A forward reaction is

• the substance that does the dissolving.

• the reaction that forms products from reactants.

• the substance that is dissolved.

• the reaction that forms reactants from products.
