Calculate the IE a one `Li^(2+)` ion b one mole of `Li^(2+)` ion.Given Rydherg constant `= 1.0974 xx 10^(7)m^(-1)`

Explanation

For ioniasion `n_(1) = 1,n_(2) = alpha`
:. Ifd is given by
a. `Delta E = Z^(2)Rhc = (9)(1.974 xx 10^(7)m^(-1))`
`xx (6.626 xx 10^(-34) Js)(3 xx 10^(8) ms^(-1))`
` = 19.638 xx 10^(-18) J`
b.`Delta E = N_(A) Delta E = (6.023 xx 10^(23)mol^(-1))`
` 1.118 xx 10^(7) J mol^(-1)`
`= 1.118 xx 10^(4) KJ mol^(-1)`
