Chemical Equilibrium and Le Chatelier's Principle

Reversible Reaction

Chemical reactions that can proceed in both directions.

Le Chatelier's Principle

System adjusts to minimize changes in equilibrium.

Dynamic Equilibrium

No net change in reactants and products over time.

Forward Reaction

Process where reactants convert to products.

Reverse Reaction

Process where products convert back to reactants.

Exothermic Reaction

Releases heat during the reaction process.

Endothermic Reaction

Absorbs heat during the reaction process.

Effect of Temperature

Adding heat favors reverse; removing favors forward.

Pressure Impact

Increased pressure favors side with fewer gas moles.

Concentration Change

Adding reactants shifts equilibrium towards products.

Equilibrium Shift

Movement towards reactants or products based on changes.

Heat Shift

Adding heat shifts reaction away from heat.

Removing Reactants

Shifts equilibrium towards reactants to compensate.

Removing Products

Shifts equilibrium towards products to compensate.

Chemical Equilibrium

State where products and reactants form at equal rates.

Gas Molecules

Changing pressure affects only gaseous reactants/products.

Equilibrium Constant

Ratio of product concentrations to reactant concentrations.

Mole Ratio

Used to determine shifts in equilibrium based on moles.

Reaction Rate

Speed at which reactants convert to products.

System Response

Equilibrium system responds to changes to restore balance.
