equally into H+ and H^*

Sahay Sir > Question Answers > equally into H+ and H^*
An element undergoes a reaction as shown: X+2e− →X 2− , energy released =30.87 eV/atom. If the energy released, is used to dissociate 4 g of H 2 molecules, equally into H+ and H^* , where H^∗ is excited state of H atoms where the electron travels in orbit whose circumference equal to four times its de Broglie’s wavelength. Determine the least moles of X that would be required. Given: I.E. of H=13.6 eV/atom, bond energy of H2 ​= 4.526 eV/ molecule.
