What is the limiting reactant for the following balanced equation when 9 moles of AlF3 are mixed with 12 miles of O2?

tamaranim1 [39]

<h2>Answer: $AlF_{3}$ </h2>

Explanation:

The chemical equation of the reaction that occurs when $AlF_{3}$ reacts with $O_{2}$ is

$4AlF_{3}+3O_{2}$ → $2Al_{2}O_{3}+6F_{2}$

$4$ moles of $AlF_{3}$ requires $3$ moles of $O_{2}$ .

$1$ mole of $AlF_{3}$ requires $\frac{3}{4}$ moles of $O_{2}$ .

Given that we have $9$ moles of $AlF_{3}$ .

$9$ moles of $AlF_{3}$ requires $\frac{3}{4}\times 9=6.75$ moles of $O_{2}$ .

But we have $12$ moles of $O_{2}$ .

So, $AlF_{3}$ will be consumed first.

So, $AlF_{3}$ is the limiting reagent.

Predict whether the reaction given is product favored or reactant favored by calculating delta G from the entropy and enthalpy c

GenaCL600 [577]

ΔG= ΔH - TΔS

YOU need to change the values to the same unit.. 42.08 J to Kj which is 42.08 x 10-3.

ΔG= (41.17) - (298K)(42.08x10-3)= 28.6 Kj/mol

because delta G is positive, it means this reaction is reactant favored.
