From the following information
`{:(A^(-)(g)rarrA^(+2)(g)+3e^(-),DeltaH_(1) = 1400 kJ//"mole"),(A(g)rarrA^(+2)(aq)+2e^(-),DeltaH_(2) = 700 kJ//"mole"),(DeltaH_(EG)[A^(+)(g)] =- 350 kJ//mol,),((IE_(1)+IE_(2))for A(g) = 950kJ//mol,):}` Find
(a) `IE_(1)` of A (b) `IE_(2)` of A (c) `DeltaH_(EG)` of A (d) `DeltaH_(HE)` of A^(2+)(g)`

Options

A. `IE_(1)` of A
B. `IE_(2)` of A
C. `DeltaH_(EG)` of A
D. `DeltaH_(HE)` of `A^(2+) (g)`

Explanation

(a) `IE_(1)` of A = 350 kJ/mol , (b) `IE_(2)` = 600 kJ/mol , (c) `Delta_(EG)` H of A = - 450 kJ/mol , (d) `Delta_(HE)` H of `(A^(2+)) = -250` kJ/mol
