Detailed Solution

In first ionization energy, we remove electron from a neutral atom, but for second ionization energy, we have to remove electron from a positive atom, where electrons are more tightly bounded due to increased nuclear attraction force and small size of cation than its neutral atom.
Hence, second ionization energy is high relative to first IP.
