Discuss the consequences of high enthalpy of H–H bond in terms of chemical reactivity of dihydrogen

Text Solution

Verified by Experts

Due to high enthalpy of H- H bond (435.88 kJ mo`l^(- 1)` ), dihydrogen is not much reactive at ordinary temperature. However, at high temperatures or in presence of catalyst It is quite reactive and forms a large number of compounds with a large number of elements. ·
