Exothermic reaction
Exothermic reaction
Releases heat energy to surroundings
Endothermic reaction
Endothermic reaction
Absorbs heat energy from surroundings
Temperature change in exothermic reaction
Temperature change in exothermic reaction
Temperature rises
Temperature change in endothermic reaction
Temperature change in endothermic reaction
Temperature drops
Activation energy
Activation energy
Minimum energy colliding particles must have for reaction
Effective collision
Effective collision
Collision that results in formation of products
Energy of products vs reactants (exothermic)
Energy of products vs reactants (exothermic)
Products have less energy than reactants
Energy of products vs reactants (endothermic)
Energy of products vs reactants (endothermic)
Products have more energy than reactants
Catalyst
Catalyst
Speeds up reaction without being used up
