Elements hydrogen reacts with other substances only slowly at room tem

1.	Elements hydrogen reacts with other substances only slowly at room temperature. Why?
Answer» In the elementary state, hydrogen exists in diatomic form i.e. as `H_(2)(g)` and the two hydrogen atoms are linked to each other by single covalent bond (H-H). Since the bond dissociation energy is very high `(435.9kJ mol^(-1))`, therefore, bond cleavage is extremely difficult. As a result, elemtal hydrogen is little reactive at room temperature.
