the electron configuration of Fe2+ is [Ar]3d6 whereas the electron configuration of Fe3+ is [Ar]365...so Fe2+ is more reactive than Fe3+???

Yes, the preferred configuration is the one that has the sub shells full or semi-full. A d subshell can take 10 electrons max. so Fe3+ with 5 electrons in 3d shell is more stable than Fe2+ (with 6 electrons). Or we can say that Fe2+ is more reactive.

I think there is a mistake that you have done for Fe3+ is [Ar] 365 instead it could be [Ar] 3d5. The statement isn't true because Fe+2 needs more electons to be stable. That is the electronegativity of Fe+2 is large than the electronegativity of Fe+3 thus Fe+3 is more reactive than Fe+2

No it doesn't make sense
