Solution
The correct option is A F, T
Heat is released in Exothermic reactions.
Energy is required for the breaking of the covalent bonds in endothermic reactions. hence this is correct , but this does not explain why heat is released in Exothermic reaction.
Correct Explanation:
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.
