Solution

The reaction is a disproportionation reaction.
It occurs in basic medium.
The oxidation number of N in $(C N)_{2}$ , $C N^{-}$ and $C N O^{-}$ is $- 3, - 2$ and $- 5$ respectively.
Cyanogen $(C N)_{2}$ is simultaneously reduced to $C N^{-}$ ion and oxidised to cyanate ion $C N O^{-}$ ion.
