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.
- Hope this Helps a little ( these are the only ones i knew)
