I think you meant Exothermic. Anways... that is a process releases energy usually in the form of heat.
to see your mom.
Exothermic, because it releases heat as a form of energy.
In an exothermic reaction, the potential energy diagram shows a decrease in potential energy as the reactants transform into products. The reactants have higher energy compared to the products, indicating that energy is released during the reaction, often in the form of heat. The diagram typically features a downward slope from the reactants to the products, with an activation energy barrier that must be overcome for the reaction to proceed. Overall, this results in a negative change in enthalpy (ΔH).
It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.
