A. the reaction is exothermic

B. the reaction is endothermic

  • Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light.
  • In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.
  • For this reason, the change in enthalpy, ΔH, for an exothermic reaction will always be negative.
  • In the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction.
