If you are given Avogadro's number of atoms of a gas '

X

'. If half of the atoms are converted into

X_{(g)}^{+}

by energy

\Delta {H}

{X}

View answer and explanation

Correct option: A

\frac{2 \Delta {H}}{\mathrm{N}_{\mathrm{A}}}

Option A (

\frac{2 \Delta {H}}{\mathrm{N}_{\mathrm{A}}}

) is correct because ionization energy is the energy required to remove an electron from one atom, and the formula correctly scales the total energy by the number of ionized atoms.
