Question

The amount of energy released when 1 * 10^8 atoms of chlorine are coverted to cl^- ions according to equation cl + e ->cl^- is 57.86 * 10^-10 j calculate electron gain enthalpy in terms of kj/mol and eV?

Answer 1

@ujjwal

Answer 2

See

u have the energy released for \(1*10^8\) atoms
So, u can calculate the energy released for 1 mol i.e. \(6.023*10^{23}\)

this energy will be in \(J mol^{-1}\)
convert it into \(kJ mol^{-1}\) using \(1 kJ = 10^3 J\)

also

\(1 eV = 1.602 ^ 10^{-19} J\)

using this find out the energy in eV
NOTE: During this last step use the energy released for \(1 atom\)
