The following phrases best describe this reaction : A Endothermic, absorbing energy

Further explanation

Delta H reaction (ΔH) is the amount of heat change between the system and its environment

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)

∆H positive (endothermic): energy (heat) is absorbed from the environment to the system

∆H negative (exothermic): energy (heat) released from the system to the environment

Reaction

H₂O(g) + energy ⇒ H₂(g) + 1/2O₂(g)

In this reaction, it is shown that to break the bonds on the H₂O molecule to form H₂ and O₂ molecules will require energy (breaking the bonds requires energy)

This energy is usually called ∆H dissociation⁰
