For reactions in which there is an increase in the kinetic energy of the products, Q is positive. The positive Q reactions are said to be exothermic (or exergic ). There is a net release of energy since the kinetic energy of the final state is greater than the kinetic energy of the initial state. Exothermic reactions in solution give out energy and the temperature increases, while endothermic reactions take in energy and the temperature decreases. Bonds are broken and made in reactions.This results in an endothermic chemical reaction—one which absorbs heat, causing a local decrease in temperature. This is in contrast to an exothermic chemical reaction, which …Endothermic and exothermic reactions can be visually represented by energy-level diagrams like the ones in Figure \(\PageIndex{2}\).
