At equilibrium, both the forward reaction and the reverse reaction occur simultaneously and at the same rate. Since the rates ar

e the same, the concentrations of the reactants and products do not change. An equilibrium constant expression can be developed, which is a mathematical expression indicating the relationship between the reactants and the products. For reactions with gases, the value of Kp can be determined using the pressures of each substance to the appropriate power. The values of Kc and Kp are related by the equation, Kp = Kc(RT)n. At 298 K, Kc = 18.3 for the following reaction. What is the value of K(p)?
C₄(s) + 4 O₂(g) ⇌ 4 CO₂(g)

Answer:

The value of the gas equilibrium constant Kp is 18.3

Explanation:

Step 1: Data given

Kp= Kc(RT)^Δn

Temperature = 298 K

Kc = 18.3

Step 2: The balanced equation

C₄(s) + 4 O₂(g) ⇌ 4 CO₂(g)

Step 3: Calculate Kp

Kp= Kc(RT)^Δn

⇒with Kp = the gas equilibrium constant =  TO BE DETERMINED

⇒with Kc = the equilibrium constant = 18.3

⇒R = the gas constant = 0.08206 L* atm/mol*K

⇒T = the temperature = 298 K

⇒Δn = mol gas phase product – mol gas phase reactant = 4-4 =0

Kp = 18.3 * (0.08206*298)^0

Kp = 18.3 * 1

Kp = 18.3

The value of the gas equilibrium constant Kp is 18.3

Consider the chemical formula for one unit of aluminum sulfate, Al2(SO4)3. How many total atoms would be present in 22 units of
EastWind [94]

Answer:

1.32×10²⁵ atoms of sulfate are contained in 22 units of it

Explanation:

1 unit = 1 mol

Al₂(SO₄)₃ → Aluminum sulfate

As 1 unit = 1 mol, 1 unit has 6.02×10²³ atoms of aluminum sulfate.

Let's make a rule of three:

1 unit of Al₂(SO₄)₃ contains 02×10²³ atoms

Then, 22 units of Al₂(SO₄)₃ must contain (22 . 6.02×10²³) / 1 = 1.32×10²⁵ atoms

Meteorologists use weather balloons to carry weather instruments high into the atmosphere. When it is first released at Earth’s
ahrayia [7]

<span>The balloons volume as it rises increases because at higher altitude external pressure is lower, so the air molecules inside the balloons tends to expand more to attain mechanical equilibrium, where the external pressure and internal pressure are equal. Unlike when the balloon is on the ground, external pressure is great so the gas molecule cannot push the walls of the balloon so it is like underinflated.</span>
