In the reaction K+O(2)rarrKO(2)...

In the reaction
`K+O_(2)rarrKO_(2)`

A

`O_(2)` acts as an oxidising agent

B

Both `K` and `O_(2)` are oxidised

C

`O_(2)` is oxidised while `K` is reduced

D

`K` acts as an oxidising agent

Text Solution

Verified by Experts

The correct Answer is:
A
`KrarrK^(o+)+e^(-)` (oxidation, acts as reducing agent)
`e^(-)+O_(2)rarrO_(2)^(1-)` ( reduction, acts as oxidising agent)
