  • What is the value of electron gain enthalpy Na+ if IE1 of Na = 5.1 eV?Option: 1 + 2.55 eV

What is the value of electron gain enthalpy Na+ if IE1 of Na = 5.1 eV?

Option: 1

+ 2.55 eV


Option: 2

+10.2 eV


Option: 3

-5.1 eV


Option: 4

-10.2 eV


Answers (1)

For, Na\rightarrow Na^{+}+e^{-}\quad I.E=5.1eV

While for, Na^{+}+e^{-}\rightarrow Na\quad \Delta H_{eg}=-5.1eV

Electron gain enthalpy of Na^{+}=-I.E\ of\ Na

Hence, the correct answer is option 3.
