Answer:

1.40 atm

Explanation:

To answer this question we can use Gay-Lussac's law, which states:

P₁T₂=P₂T₁

When volume and number of moles remain constant.

P₁ = 1.11 atm

T₁ = 23°C ⇒ 23+273.16 = 296.16 K

T₂ = Boiling point of water = 100 °C ⇒ 100+273.16 = 373.16 K

P₂ = ?

We put the known data in the equation and solve for P₂:

1.11 atm * 373.16 K = P₂ * 296.16 K

P₂ = 1.40 atm

Answer: 1.8 moles Fe and 2.7 moles $CO_2$ are produced.

Explanation:

The balanced chemical reaction is:

$Fe_2O_3+3CO\rightarrow 2Fe+3CO_2$

According to stoichiometry :

3 moles of $CO$ require 1 mole of $Fe_2O_3$

Thus 2.7 moles of $CO$ will require= $\frac{1}{3}\times 2.7=0.9moles$ of $Fe_2O_3$

Thus $CO$ is the limiting reagent as it limits the formation of product and $Fe_2O_3$ is the excess reagent.

As 3 moles of $CO$ give = 2 moles of $Fe$ and 3 moles of $CO_2$

Thus 2.7 moles of $CO$ will give = $\frac{2}{3}\times 2.7=1.8moles$ of $Fe$ and $\frac{3}{3}\times 2.7=2.7moles$ of $CO_2$

Thus 1.8 moles Fe and 2.7 moles $CO_2$ are produced.
