For the reaction 2Fe + 3Cl2 → 2FeCl3 which of the following options gives the correct reactant:reactant ratio?

A. Fe:Cl2 = 1:1

B. Fe:Cl2 = 2:3

C. Fe:Cl2 = 3:2

D. Fe:FeCl3 = 1:1

Respuesta :

Fe:Cl2 = 2:3

You just use the subscripts.

Answer: The correct answer is Option 2.

Explanation:

For the given reaction:

[tex]2Fe(s)+3Cl_2(g)\rightarrow 2FeCl_3(s)[/tex]

By Stoichiometry of the reaction:

2 moles of iron reacts with 3 moles of chlorine gas to produce 2 moles of iron chloride.

The stoichiometric coefficient of iron = 2

The stoichiometric coefficient of chlorine = 3

Mole ratio of Iron : Chlorine = Stoichiometric coefficient of Iron : Chlorine = 2 : 3

Hence, the correct answer is Option 2.
