1.	Ionisation potential of hydrogen in kJ mol-1 unit is1312.0. What will be its value in unit of eV atom-l[IeV 1.6 x 10-19J1 2
Answer» eV = electronvolt kJ =kilojoule 1eV= 1.6021765×10⁻²²kJ We first convert kJ to Ev eV = 1312/(1.6021765×10⁻²²) = 8.18886 x 10^24 Then we convert to Ev/Atom by dividing byAvogadro’s number eV/Atom = (8.18886 x 10^24)/6.022x10^23) = 13.6

Ionisation potential of hydrogen in kJ mol-1 unit is1312.0. What will be its value in unit of eV atom-l[IeV 1.6 x 10-19J1 2

Answer»

eV = electronvolt

kJ =kilojoule

1eV= 1.6021765×10⁻²²kJ

We first convert kJ to Ev

eV = 1312/(1.6021765×10⁻²²) = 8.18886 x 10^24

Then we convert to Ev/Atom by dividing byAvogadro’s number

eV/Atom = (8.18886 x 10^24)/6.022x10^23)

= 13.6
