🔥Exothermic reaction
- ✓Any reaction that releases energy
- ✓Broad category of reactions
- ✓Includes neutralization and respiration
- ✓Negative enthalpy change
- ✓Does not require oxygen
🔥Combustion
- ✓A specific exothermic reaction
- ✓Reaction of a fuel with oxygen
- ✓Produces heat and usually light
- ✓Often forms carbon dioxide and water
- ✓Examples: burning wood, gas or fuel
Verdict
Combustion is one kind of exothermic reaction, requiring a fuel and oxygen. All combustion releases energy, but many exothermic reactions need no oxygen at all.
Frequently asked
Is all combustion exothermic?+
Yes. Combustion always releases energy, making it a type of exothermic reaction.
Are all exothermic reactions combustion?+
No. Neutralization and respiration release energy without being combustion.
What does combustion need?+
Combustion requires a fuel and oxygen, plus enough heat to start.
