1. Balanced Chemical Equation:

The balanced chemical equation for the reaction is:

2 KI + F₂ → 2 KF + I₂

2. Mole Ratio:

From the balanced equation, we see that 1 mole of F₂ reacts to produce 1 mole of I₂.

3. Calculate Moles of Iodine:

Since the mole ratio is 1:1, 0.72 moles of F₂ will produce 0.72 moles of I₂.

4. Convert Moles to Grams:

* The molar mass of iodine (I₂) is 253.8 g/mol.

* Grams of I₂ = moles of I₂ × molar mass of I₂

* Grams of I₂ = 0.72 mol × 253.8 g/mol

* Grams of I₂ = 182.7 g

Therefore, 182.7 grams of iodine are produced when 0.72 mol of fluorine reacts with potassium iodide.
