The elecron affinity of chlorine is 3. 7...

The elecron affinity of chlorine is `3. 7 eV`. How much energy in kcal is released when `2g` chlorine is completely converted to `cl^-` ion in a gaseous state ?
`(1 eV = 23. 06 kcal "mol"^(-10))`.

Text Solution

Verified by Experts

`Cl + e^(-) to Cl^(-) + 3.7 eV`
`35.5 " " 3.7 xx 23.06` kcal
`therefore` Energy released for conservation of 2 g gaseous chlorine into `Cl^(-)` ions
`= (3.7 xx 23.06)/(35.5) xx 2 = 4.8` kcal
