Refresh for final

[Susie 2D]

Can someone give me a quick refresh of Le Chatlier's principle?

[106033555]

honestly i just think it talks about a system being disturbed and wanting to be in equilibrium.

pressure
if pressure increases, volume decreases, equilibrium shifts to side with less mols
if pressure decreases, volume increases, equilibrium shifts to side with more mols

temperature
for endothermic:
increase in temp, shift towards products
decrease: shift towards reactants
for exo:
increase in temp, shift towards reactants
decrease: shift towards products

concntration:
add more reactants, reaction favors products
add more products, reaction favors reactants

Hi!

Le Chatelier's Principle is the idea that when a system at equilibrium is subjected to change, processes happen that counteract this change, resulting in new states of equilibrium. There are three main components of Le Chatelier's Principle: concentration and partial pressure change, total pressure and volume change, and temperature change. Regarding concentration and partial pressure change, if they both increase, equilibrium will shift away from that side and if they decrease, then the equilibrium will shift toward that side. If the total pressure increases or volume decreases, the equilibrium shifts toward the side with fewer molecules. On the other hand, if total pressure decreases or volume increases, then the equilibrium will shift toward the side with more molecules. Lastly, if temperature increases, equilibrium shifts towards the endothermic direction, and if the temperature decreases, the equilibrium shifts away from the endothermic direction. When heat is endothermic, heat is positive and required. When heat is exothermic, heat is negative and released.

Le Chatelier’s Principle: if a system in equilibrium experiences a change in concentration, pressure, temperature, or volume, the system will adjust itself to restore equilibrium and counteract that change.
