                                             Exothermic Reactions

A chemical reaction can be defined as a process that includes rearranging the atoms of one or more substances to form a new one. Chemical reactions that produce heat are known as exothermic reactions. Energy in the form of heat is transferred to the surroundings. Combustion is an example of exothermic reactions. These reactions occur in many applications of daily life. The term exothermic is a combination of two words, ‘Exo’ means exit and ‘therm’ means heat. The term supports its definition completely.

Quick Facts: –

  • Exothermic reactions may occur impulsively and result in higher entropy of the system.
  • These reactions occur when the energy used to break bonds in the reactants is less than the energy released after formation of new bonds.
  • This evolution of heat results in the increase of temperature of the system.
  • Some examples of exothermic reactions are neutralization, burning etc.
  • The easiest and most readily available exothermic reaction is the one between detergent and water.
  • The net energy change in these reactions is positive.
  • The reactants have more energy than the end products.
  • The increased temperature can be measured using a thermometer.
  • These reactions are denoted by a negative heat flow.
  • In the laboratory, exothermic reactions can be explosive sometimes.
  • Sometimes they also involve toxic chemicals along with extreme heat.
