The main reason is :-----------
⏹“Half-filled and fully-filled orbitals are extra stable”⏹
✔️The d subshell has five orbitals, which can accommodate a maximum of 10 electrons.
✔️Now Fe+3 (3d5) has half filled orbitals which provide extra stability to it because of symmetrical configuration.
✔️But Fe+2(3d6) has one electron more than the symmetrical arrangement.
✔️So we can say that Fe+3 is more stable than Fe+2....

For certain. Fe has an electron configuration ...3d(6)4s². Fe(+2) has 3d(6), by losing both 4s electrons. Fe(3+), besides losing these 2 loses also 1 electron 3d - and gets a structure of 3d(5), much more stable than 3d(6). Orbitals are more stable when empty, half- or completely full
therefore Fe+3 is more stable than Fe+2
