Calculated the energy required to excite one litre of hydrogen gas at `1atm` and `298K` to the first excited state of atomic hydorgen. The enegry for the dissociation of `H-H` bond is `436 kJ mol^(-1)`.

Answer

`97.819 KJ`

Explanation

Bond dissociation energy requried =no. of moles `xx("H-H bond disssciation energy" +2xx(13.6)/(4))`
`DeltaE=97.819 KJ`
