In an endothermic reaction, energy is absorbed from the surroundings, while in an exothermic reaction, energy is released into the surroundings.
- 2
The amount of energy released or absorbed in a chemical reaction can be controlled by changing the amount or type of reactants.
- 3
The rate at which energy is absorbed or released can be controlled by changing the amount of reactants, temperature, or distribution of particles.
