Answer:

2CO₂ ⇄ 2CO + O₂.

Explanation:

  • <em>The equilibrium constant (Keq)</em> for a reaction is the ratio of the concentration of the products to the reactants, each one is raised to each molar coefficient.

So, for Keq = [CO]²[O₂]/[CO₂]²,

It is clear that the products are CO and O₂, while the reactant is CO₂.

So, the reaction for this is:

<em>2CO₂ ⇄ 2CO + O₂.</em>

What is the mass of 2N at 0.2829 atm 1.35 L and 25°C
maria [59]
<h3>Answer:</h3>

0.437 g

<h3>Explanation:</h3>

From the question we have;

Pressure of the gas as 0.2829

Volume of the gas as 1.35 L

Temperature of the gas as 25°C

But, K = °C + 273.15

Therefore, temperature of the gas is equivalent to 298.15 K

We are required to calculate the mass of the gas

<h3>Step 1: Number of moles of the gas </h3>

Using the ideal gas equation, PV = nRT , we can determine the number of moles.

R is the ideal gas constant, 0.082057 L.atm/mol.K

Therefore, rearranging the formula;

n = PV ÷ RT

 = (0.2829 atm × 1.35 L) ÷ (0.082057 × 298.15 K)

 = 0.0156 mole

Therefore, the number of moles of the gas is 0.0156 mole

<h3>Step 2: Mass of the gas </h3>

We know that mass of a compound is the product of moles and the molar mass.

Mass = Moles × Molar mass

Molar mass of the gas is 28.0134 g/mol

Therefore;

         = 0.0156 mole × 28.0134 g/mol

         = 0.437 g

Thus, the mass of the gas is 0.437 g
