Given the balanced equation:


2KI F2 ā†’ 2KF I2


Which type of chemical reaction does this equation represent?


(1) synthesis

(2) decomposition

(3) single replacement

(4) double replacement

Verified Answer :

Answer: Option (3) is the correct answer.

Explanation:

When a more reactive element or atom replaces a less reactive atom then this type of reaction is known as single displacement reaction.

In the given reaction, potassium iodide reacts with fluorine and results in the formation of potassium fluoride and iodine.

Here, fluorine being more reactive displaces iodine from potassium iodide.

Therefore, it is a single replacement or displacement reaction.

What is a balanced equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.

Let's consider the following balanced equation.

2 KI + Fā‚‚ ā†’ 2 KF + Iā‚‚

Which type of chemical reaction does this equation represent?

  1. synthesis. No, since in a synthesis there is only one product.
  2. decomposition. No, since in a decomposition there is only one reactant.
  3. single replacement. Yes. Fluorine replaces iodine in potassium iodine.
  4. double replacement. No, since there is only one replacement.

The given balanced equation represents a single replacement reaction.
