What is the characteristic of an exothermic reaction?

  1. Requires added heat source

  2. Self cooling

  3. Self heating

  4. Processes faster without heat

The correct answer is: Self heating

An exothermic reaction is a chemical reaction that releases energy in the form of heat. This means that it is self-heating and does not require an added heat source to take place. Option A is incorrect because it is the opposite of what an exothermic reaction does. Option B is incorrect because exothermic reactions do not cool themselves, they heat up. Option D is incorrect because exothermic reactions actually release heat energy, not process faster without heat.
