Striking a match, Endothermic or Exothermic?

Click For Summary
SUMMARY

Striking a match is an exothermic reaction, as it releases heat during combustion. The initial heat required to ignite the match is related to activation energy, not the overall thermodynamic nature of the reaction. While the ignition process requires heat, the subsequent reaction produces more heat than is consumed, confirming its exothermic classification. Therefore, the assertion that the reaction is endothermic due to the initial heat requirement is incorrect.

PREREQUISITES
  • Understanding of thermodynamics concepts, specifically endothermic and exothermic reactions.
  • Familiarity with activation energy and its role in chemical reactions.
  • Basic knowledge of combustion processes.
  • Ability to differentiate between heat absorption and heat release in chemical reactions.
NEXT STEPS
  • Research the concept of activation energy in chemical reactions.
  • Study the differences between endothermic and exothermic reactions in detail.
  • Explore combustion chemistry and its thermodynamic properties.
  • Investigate real-world examples of exothermic reactions beyond combustion.
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding the principles of thermodynamics and chemical reactions.

Homework Statement



I was wondering whether striking a match is endothermic or exothermic.

Homework Equations

The Attempt at a Solution



This seems quite straight forward as striking a match releases heat, which is obviously exothermic. However, the process of igniting the match requires heat in itself, so I was wondering since the reaction required heat, would it be endothermic instead? I read from a post somewhere that for a reaction to be endothermic, heat is absorbed for the reaction to occur. Since heat is required for the initial ignition of the match, wouldn't that be an endothermic reaction? As well, is the bolded statement correct?

You are confusing the activation energy needed to trigger a reaction with whether the reaction is endothermic or exothermic. Since this is marked as homework, I'll leave it at that for now.
