• 50 cal

• 25 cal

• 55 cal

• 70 cal

1. In an endothermic process:

• The system gains heat

• The system loses heat

• The system heats its surroundings

• The system takes heat from its surroundings

In an exothermic process:

• The system stays at a neutral temperature

• The system heats up

• The system cools down

• the system heats up its surroundings

• The Chemical Equilibrium is established when

• [reactants] = [products]

• [reactants] doesn't = [products]

• Le Chatelier’s Principle states that when a change is applied to a system at equilibrium, the system will shift in a direction that relieves the stress.

• The system will shift in a direction that relieves the stress.
• The system will shift in a direction that increases the stress.
