Consider the following changes :
$$\eqalign{
& \left( {\text{i}} \right)M\left( s \right) \to M\left( g \right) \cr
& \left( {{\text{ii}}} \right)M\left( s \right) \to {M^{2 + }}\left( g \right) + 2{e^ - } \cr
& \left( {{\text{iii}}} \right)M\left( g \right) \to {M^ + }\left( g \right) + {e^ - } \cr
& \left( {{\text{iv}}} \right){M^ + }\left( g \right) \to {M^{2 + }}\left( g \right) + {e^ - } \cr
& \left( {\text{v}} \right)M\left( g \right) \to {M^{2 + }}\left( g \right) + 2{e^ - } \cr} $$
The second ionization energy of $$M$$ could be calculated from the energy values associated with :
A.
(i) + (iii) + (iv)
B.
(ii) - (i) + (iii)
C.
(i) + (v)
D.
(v) - (iii)
Answer :
(v) - (iii)
Solution :
Second ionization energy is amount of energy required to take out an electron from the monopositive cation.
