Question

The electron gain enthalpy of chlorine is -349 kJ mol. How much energy (in kJ) is released when 1g of
chlorine is completely converted into chloride ion in a gaseous state?​

Answer 1

Answer:

In the process Cl(g)+e

ΔH

Cl(g),ΔH is negative.

The process represents electron gain enthalpy of chlorine. Energy is released when an electron is added to the gaseous chlorine atom. Chlorine has the most negative value of electron gain enthalpy. It is equal to -348.3 kJ/mole.
