  • If it is given that it requires energy to ionise 0.1 mole of a gas <img alt="\mathrm{ 'X' \: into \: 'X^{+}{}',}

If it is given that it requires \mathrm{\Delta H} energy to ionise 0.1 mole of a gas \mathrm{ 'X' \: into \: 'X^{+}{}',} the Ionisation Energy \mathrm{ (IE) }of \mathrm{X} is

(Where \mathrm{N_A} is Avogadro's number.)

Option: 1

\mathrm{\Delta H/N_A}


Option: 2

\mathrm{0.1\Delta H/N_A}


Option: 3

\mathrm{10\times\Delta H/N_A}


Option: 4

None of the above

If 0.1 moles are ionised by energy \mathrm{\Delta H}

1 mole (\mathrm{N_A} atom) will be ionised using \mathrm{10 \times \Delta H}

1 atm will require \mathrm{10 \times \Delta H/N_A} energy ionise.

Hence option 3 is correct.
