Why does reducing power of trioxide decrease down a group ?

Geetha · Accepted Answer

First of all be specific with which group Mohammed Anyway I guess
your question as the reducing power of trioxide of group 15 It
decreases down the group, as the size increases the gain of
electron is tough because of electron -electron repulsion As gain
of electron needs more energy their electrode potential are high
Higher the oxidation potential less will be the reducing power
