Final answer:
The reaction Cl₂ + 2Kl → 2KCl + I₂ is an example of a single-displacement reaction.
Step-by-step explanation:
The given reaction: Cl₂ + 2Kl → 2KCl + I₂ is an example of a single-displacement reaction. In a single-displacement reaction, one element is replaced by another element in a compound. In this reaction, chlorine (Cl₂) replaces iodine (I) in potassium iodide (KI), forming potassium chloride (KCl) and iodine (I₂).
