Final answer:
The reaction Cl₂(g) + 2KBr(aq) → 2KCl(aq) + Br₂(l) is a displacement reaction.
Step-by-step explanation:
The reaction Cl₂(g) + 2KBr(aq) → 2KCl(aq) + Br₂(l) is a displacement reaction.
In a displacement reaction, one element replaces another element in a compound. In this reaction, chlorine gas replaces bromine in potassium bromide, resulting in the formation of potassium chloride and liquid bromine.
Therefore, the correct answer is c. Displacement reaction.
