When a reaction gives out heat energy (temperature rise)
What is an endothermic reaction?
When a reaction absorbs heat energy (temperature drops)
What is activation energy?
The minimal amount of energy needed to start a chemical reaction. It is energy that reacting particles have to overcome before collisions can be reactions
Does energy go up or down in an exothermic reaction?
Energy is given out so overall amount goes down
Does energy go up or down in an endothermic reaction?
