Thermochemistry and Equilibrium
Endothermic and Exothermic Reaction
Heat is being released
Reactants have more energy than the products
Heat is absorbed
Reactants have less energy than the products
Le Chatelier’s principles
If a system at equilibrium is exposed to a stress, the system will shift so as to relieve that stress.
Types of stress
Reversible reactions and Le Chatelier’s principles
Only goes in one direction
The product can turn back into the reactant and the other way around.
At some point the rate of the forward reaction and backward reaction are equal. Equilibrium has been reached.
At equilibrium, the concentration of the reactants and the products have stopped changing.
