Given `DeltaH` for the process `Li(g)rarrLi^(+3)(g) + 3e^(-)` is `19800kJ//"mole" & IE_(1)` for `Li` is `520` then `IE_(2) & IE_(1)` of `Li^(+)` are respectively (approx value) :-
(a). `11775,7505`
(b). `19280,520`
(c). `11775,19280`
(d). data insufficient

A

`"7505,11775"`

B

`"520,19280"`

C

`"11775,19280"`

D

Data issufficient

Text Solution

Verified by Experts

The correct Answer is:
A
`IE_(3)=13.6xx32eV//"atoms"`=`118 09.155 KJ//"mole"`
`~~ 11775KJ//"mole"`
`IE_(2)=19800-IE_(1)-IE_(3)=3505 KJ//"mole"`
