Through exothermic reaction
What is an exothermic reaction
A reaction where energy is released to the surroundings
What is endothermic reaction
A reaction that absorbs energy from the surroundings
Examples of exothermic reactions
Combustion
Neutralisation
Examples of endothermic reactions
Photosynthesis
Melting
What is collision theory
A scientific explanation of how chemical reactions occur
What is activation energy
The minimum amount of energy needed for a chemical reaction to occur
What are the energy changes in breaking and making bonds
Energy is absorbed for breaking bonds, (endothermic process). Energy is released when making bonds, (exothermic process).
