The chemical equilibrium is:

3H_2(g) + N_2(g)\leftrightharpoons 2NH_3(g) + Q

The best conditions, taking into account Le Chatelier's Principle, will be low temperature and high pressure, because is an exothermic reaction and there are more moles of gases in the reactants than in the products.

At 500K, the equilibrium constant for the reaction N2O4D2NO2 is 1.5 x 10^3. What is the equilibrium constant for the reaction: 6
Veronika [31]

Answer:

K = 2.96x10⁻¹⁰

Explanation:

Based on the initial reaction:

N2O4 ⇄ 2NO2; K = 1.5x10³

Using Hess's law, we can multiply this reaction changing K:

3 times this reaction:

3N2O4 ⇄ 6NO2; K = (1.5x10³)³ =3.375x10⁹

The inverse reaction has a K of:

6NO2 ⇄ 3N2O4 K = 1/3.375x10⁹;

<h3>K = 2.96x10⁻¹⁰</h3>

How many grams of CO are needed with an excess of Fe2O3 to produce 35.0 g Fe? Please show work.
Dominik [7]
We must first write out the entire equation for this reaction which is as follows:

CO + Fe2O3 --> Fe + CO2

Now we must balance this equation which provides us with the following equation:

3 CO + Fe2O3 --> 2Fe + 3 CO2

We are told that we have excess Fe2O3, so that suggests that CO is the limiting reagent. We now simply convert the mass of Fe given to moles of Fe, and convert moles of Fe to moles of CO.

35.0 g Fe/ 55.845 g/mol = 0.627 moles Fe

0.627 moles Fe x (3 moles CO)/(2 moles Fe) = 0.940 moles CO

Now with the moles of CO present, we simply convert this back to mass using the molecular weight of CO.

0.940 moles CO x 28.01 g/mol = 26.3 g CO.

Therefore, 26.3 g of CO are needed to produce 35.0 g of Fe. Since we began with three significant figures in our starting mass, our answer must also have three significant figures.
