In the formation of $X^{+ 2}_{(g)}$ from $X^{+}_{(g)}$ , 4 eV energy is absorbed, which would be equal to :

Options:

Answer:

Solution:

The process described is the removal of an electron from a unipositive gaseous ion ( $X_{(g)}^{+}$ ) to form a dipositive gaseous ion ( $X_{(g)}^{+ 2}$ ). This energy change corresponds to the second ionization energy (IE₂) of element X.

The reaction is:

$X_{(g)}^{+} \to X_{(g)}^{+ 2} + e^{-}$

The energy absorbed, 4 eV, is therefore the second ionization energy of X.
