Question

What is the theoretical yield for CCl4 reacting with 100.0 grams of Cl2 with excess CS2.

Answer 1

Theoretical yield of CCl₄ = 72.3 g

Step-by-step explanation:

Given data:

Mass of Cl₂ = 100.0 g

Theoretical yield of CCl₄ = ?

Solution:

Chemical equation:

CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂

Number of moles of Cl₂ :

Number of moles = mass/molar mass

Number of moles = 100 g/ 71 g/mol

Number of moles = 1.41 mol

Now we will compare the moles of Cl₂ with CCl₄ .

Cl₂ : CCl₄

3 : 1

1.41 : 1/3×1.41 = 0.47 mol

Theoretical yield of CCl₄ :

Mass = number of moles × molar mass

Mass =0.47 mol × 153.82 g/mol

Mass = 72.3 g
