Equilibrium, Le Chatelier, Reaction Rates

Le Chateliers principle

________: If stress is placed on a system at equilibrium, the system will proceed in a direction that minimizes the stress.

Chemical equilibrium

________ can be altered by concentration, temperature, and /or pressure.

reaction rate

An increase in concentration increases the ________, and vice versa.

Enzyme

________: a naturally occurring catalyst.

proportional change

Defined as the ________ in concentration of a reactant or product.

solid liquid

Increased temperature means particles move faster (think ________ gas)

Reactants

________ must collide with correct orientation (angle) and with enough energy.

Catalyst

________: a substance that increases reaction rates but isnt in the reaction.

Concentration

________: density /amount of a substance (how much is there ?)

Equilibrium

________: a balance.

right

Shifting ________: if more products are being created than reactants.

Equilibrium constant

________: concentration of products over reactants, KEQ.

surface area

An increase in ________ increases the reaction rate, and vice versa.

Reversible reaction

________: one that moves forward and reverse without using extra energy.

reaction rate

An increase in pressure increases the ________, and vice versa.

Catalysts

________ work by reducing the activation energy (energy to break /form bonds)

Chemical equilibrium

________: reversible reaction creating reactants /products (at same rate)

reaction rate

An increase in temperature increases the ________, and vice versa.

reaction rate

A catalyst increases the ________, and a inhibitor decreases the ________.
