Question

The difference between ionisation enthalpy change and its ionization energy is

Answer 1

Answer:

Explanation:

Ionisation energy is defined as an amount of energy required for removal of electron from outermost orbit in an isolated gaseous atom

Ex. A(g)gives A+(g) + e-

Whereas

Ionisation enthalpy is ◇H i.e. change in energy

It is -ve when reaction is exothermic

And +ve when reaction is endothermic

Ex. Cl^2-=cl^- +e^- ◇H is -ve

Hcl=h^+ + cl^- ◇H is +ve
