Consider the following ionization steps : M(g) rarr M^(+)(g) +e^(-), DeltaH=100eV M(g) rarr M^(2+)(g)+2e^(-),DeltaH=250eV Select correct statement(s)

M_((g)) rarr M_((g))^(+) +e^(-), DeltaH = 100eV M_((g)) rarr M_((g))^(2+) +2e^(-), DeltaH = 250 eV which is incorrect statement?

In the process , Cl(g) + e^(-) overset(DeltaH)(to)Cl^(-)(g) , DeltaH is

A^(+)(g) rarr A(g) DeltaH =- 2eV 2A(g) rarr 2A^(+) (g) DeltaH = x Find the value of x in eV.

The formation of the oxide ion O_(g)^(2-) requires first an exothermic and then an endothermic step as shown below: O_(g)+e^(-) rarr O_(g)^(-) , DeltaH=-142 kJ mol^(-1) O(g)+e rarr O_(g)^(2-) , DeltaH=844kJ mol^(-1) This is because:

If {:(X(g)^(-) rarr X(g)^(2) +3e^(-),DeltaH_(1)= 900 kJ),(X(g) rarr X(g)^(2+),DeltaH_(2)=650kJ):} Then find DeltaH_(eg) of X.
