4. If the heat of reaction is written on the reactant side of a chemical equation, what does that indicate about the reaction?
ng
It is an exothermic reaction.
The energy of the products is less than the energy of the reactants.
hanges
It requires heat for the reaction to occur.
ate
The reaction will release that amount of heat to the surroundings.
