Types of Reactions

Endothermic Reaction

An endothermic reaction absorbs energy from its surroundings. Example: Photosynthesis.

Example Equation: 6CO₂ + 6H₂O + Energy → C₆H₁₂O₆ + 6O₂

Exothermic Reaction

An exothermic reaction releases energy to its surroundings. Example: Combustion of methane.

Example Equation: CH₄ + 2O₂ → CO₂ + 2H₂O + Energy
