help me in this question
Dear student,
Hydrogen (H2) exists as a diatomic molecule i.e two H atoms are bonded as H-H. In order for H to react the H-H bond has to break, which requires energy (this energy is called bond enthalpy of H molecule).
As this energy required to break that bond is large, breaking of H-H bond is difficult at room temperature, making hydrogen inert.
Regards
