Question

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

Answer 1

Theoretical yield is 216.88 grams when reacting with 100.0 grams of Cl2 with excess CS2.

Step-by-step explanation:

Theoretical yield is the complete conversion of a limiting reagent in product.

In the equation given

3Cl2 + CS2 ⇒ CCl4

100 grams of Cl2 will give

number of moles =
`(mass given)/(atomic mass)`

=
`(100)/(70.906)`

= 1.41 moles

3 moles of Cl2 gives 1 mole of CCl4

1.41 moles of Cl2 will give x moles of CCl4

`(1)/(3)` =
`(x)/(1.41)`

0.47 moles of CCl4 is formed

Theoretical yield is 0.47 x 153.82

= 216.88 grams.

100 gram of Cl2 is the limiting reagent in the reaction which produced 216.88 grams of CCl4.
