Answer:
It is an example of single displacement reaction.
Step-by-step explanation:
Single replacement reaction:
A single element replaces another element in a compound.
For example,
![AB+C\rightarrow A+BC](https://img.qammunity.org/2020/formulas/chemistry/middle-school/astdrmt2hx6tjahd2znb332cc6bvro7spz.png)
The given reaction is as follows.
![AlBr_(3)+3K\rightarrow 3KBr+Al](https://img.qammunity.org/2020/formulas/chemistry/middle-school/2w4dkgsnkgvh0kv4uc11jpwgwod61icirx.png)
In the above reaction, aluminium bromide is dissociated into the
, these bromide ions are reacted with potassium atoms to form potassium bromide.
Here, only one element displaces therefore, it is an single displacement reaction.
