Answer:
The answer to your question is Exothermic reaction
Step-by-step explanation:
Data
C₃H₈ + 5O₅ ⇒ 3CO₂ + 4H₂O Δ H = -2221 kJ/mol
Endothermic reactions are chemical reactions that need a supplement of energy to proceed.
Exothermic reactions are chemical reactions that release energy, they do not need energy to proceed.
ΔH indicates if the reaction is endothermic or exothermic if ΔH is positive the reaction is endothermic if ΔH is negative the reaction is exothermic.
