If heat is written on the product side and the container is hot, what is the nature of the reaction?
Answer and explanation
Correct answer: Exothermic
In a thermochemical equation, heat written on the product side means that the reaction releases heat to the surroundings. The surroundings, including the container, therefore become warm. Such a reaction is called exothermic, so option A is correct. An endothermic reaction would absorb heat and generally cause cooling. Electrolytic decomposition and precipitation describe different reaction features and do not follow from the temperature observation.
