If heat is written on the reactant side of an equation, what type of reaction is it?

Answer and explanation

Correct answer: Endothermic

The position of heat in an equation indicates the energy transfer. When heat is written on the reactant side, the reaction must absorb that heat in order to proceed. Such a reaction is called endothermic, so option B is correct. An exothermic reaction places released heat on the product side; combustion is often exothermic, and precipitation refers to solid formation.
