Asked in ETEA MDCAT 2009 2009Moderate

Thermite process is:

Correct answer: A. Exothermic

  • A. Exothermic
  • B. Endothermic
  • C. Reversible
  • D. None of above

Explanation

Exothermic: An exothermic reaction is a chemical reaction that releases energy in the form of heat. In the case of the thermite process, it is indeed exothermic. The reaction involves the highly exothermic oxidation-reduction reaction between a metal oxide and a reducing agent, usually aluminum. The reaction produces a significant amount of heat, resulting in a rapid increase in temperature and the generation of intense heat and light. The exothermic nature of the thermite process makes it useful for various applications, such as welding and incendiary devices.

About Exothermic and Endothermic Reactions

Exothermic reactions release heat to the surroundings and have negative enthalpy change, while endothermic reactions absorb heat and have positive enthalpy change. The topic uses energy profiles to identify reactants, products and activation energy, and includes bond energy, enthalpy diagrams, calorimetry and Hess's law for calculating overall heat changes.
