Oxidation state of P in reactant = 0
Oxidation state of P in product = +7
So, P is oxidised.
P4 is reducing agent
Oxidation state of Se in reactant = 0
Oxidation state of Se in product = -2
So, Se is reduced
Se is oxidising agent
Answer:
The substance oxidised is P
The substance reduced is Se
The oxidiizing agent is Se
