Question

Balance the following equation and determine the mole ratio of Cl2 to CCl4. CS2 + Cl2 CCl4 + S2Cl2

)A) 1:1
)B) 2:4
)C) 1:2
)D) 3:1
)E) 1:3

Answer 1

CS₂ + Cl₂ → CCl₄ + S₂Cl₂ [unbalanced equation]

CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂ [balanced equation]

∴ the mole ratio of Cl₂ : CCl₄ is 3 : 1 (option D)

Answer 2

Answer : The correct option is, (D) 3 : 1

Explanation :

The balanced chemical equation will be,

`CS_2+3Cl_2\rightarrow CCl_4+S_2Cl_2`

By the stiochiometry, 1 mole of carbon sulfide react with 3 moles of chlorine to give 1 mole of carbon tetrachloride and 2 moles of sulfur chloride.

From the balanced chemical reaction, we conclude that the mole ratio of
`Cl_2` to
`CCl_4` is, 3 : 1

Hence, the correct option is, (D) 3 : 1
