Question

What types of energy are involved in a chemical reaction?

is the energy required for a chemical reaction to take place, and
is the energy associated with
every substance.

Answer 1

The types of energy in chemical reactions are as follows: internal energy, enthalpy

Step-by-step explanation:

The internal energy is the sum of all the energies, it is due to the positions and movements of the subatomic particles, atoms and molecules that constitute it, as well as to the unions between the atoms. In chemical reactions there is a variation in the internal energy of substances, classified as exothermic if they release energy in the form of heat, endothermic if they absorb energy in the form of heat.

On the other hand, the enthalpy of reaction is the heat absorbed or released in a chemical reaction at a constant pressure. It is defined as the subtraction between the sum of the enthalpies of the products and the sum of the enthalpies of the reagents.

Answer 2

Enthaply

Step-by-step explanation:

The Energy involved in a chemical reaction is the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.
