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

Theoretical yield of CCl₄ =  72.3 g

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

the answer is d. 74.02
