Chapter 20: Reversible Reactions

Le Chateliers Principle

________ is the idea that if you change the conditions of a reversible reaction at equilibrium, the system will try to counteract that change.

Blue copper sulfate

________ is described as hydrated.

symbol ⇌

The ________ has two half arrowheads, one pointing in each direction.

reverse reaction

The forward reaction is endothermic and the ________ is exothermic.

N2 + 3H2 with pressure

2NH3

position of equilibrium depends on conditions

temperature, pressure and concentration

anhydrous copper sulphate+water exothermic

hydrated copper sulfate

hydrated copper sulfate endothermic

anhydrous copper sulphate+water

reversible reactions can be

___exothermic and endothermic

if you decrease the temperature

_______the equilibrium will move in the exothermic direction to produce more heat

if you increase the concentration

____of the reactants the system tries to decrease it again

if you decrease the concentration

____of products the system tries to increase it again

if you change the concentration of either

__the reactants or the products the system will no longer be at equilibrium

reactions are

endothermic in the other

all reactions are

___exothermic in the one direction

N2+3H2 with concentration

2NH3

N2+3H2 with temperature

2NH3
