Ionisation potential fo hydrogen is 1312...

Ionisation potential fo hydrogen is 1312`kJ*mol^(-1)` Express the value in `eV*"atom"^(-1)`. (`1eV=1.6xx10^(-19)`)

Text Solution

Verified by Experts

Ionisation potential of hydrogen`=1312.0kJ*mol^(-1)`
`=(1312xx10^(3))/(6.023xx10^(23))J-"atom"^(-1)`
`=(1312xx10^(3))/(6.023xx106(23))xx(1)/(1.6xx10^(-19))eV*"atom"^(-1)`
`=13.61eV*"atom"^(-1)`.
