Answer:

Decomposition reaction.

Explanation:

2HI —> H₂ + I₂

From the above equation, we can see clearly that HI undergoes a reaction to produce H₂ and I₂ which are the elements that make up HI.

Therefore, the equation illustrated above is a decomposition reaction because HI breaks into H₂ and I₂

NOTE: Decomposition reaction is a reaction in which a compound splits or breakdown into two or more simple elements or compound.
