Question

Endothermic reactions are characterized by ..
..............
.... of energy​

Answer 1

Answer:

When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).

Answer 2

Explanation:

A chemical reaction will either absorb energy from its surroundings or release energy into its surroundings. A reaction that absorbs energy is said to be endothermic. In an endothermic reaction, the starting materials (reactants) are more stable than the products; they are in a lower energy state.
