The equilibrium constant, Kc, for the reaction below is 0.10 at 25oC. Find the equilibrium concentration of chlorine gas, Cl2(g), if the equilibrium concentrations of ICl(g) and I2(g) are known to be 0.50 M and 0.40 M respectively.

2 ICl(g) → Cl2(g) + I2(g)

Answers

Answer:

The equilibrium concentration of chlorine gas, Cl₂(g), is 0.0625 M

Explanation:

Chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed, so that no changes are observed as time passes, despite the fact that the substances present continue to react with each other.

The mathematical expression that represents Chemical Equilibrium is known as the Law of Mass Action and is stated as: The ratio of the product of high concentrations to the stoichiometric coefficients in the reaction of products and reactants remains constant at equilibrium. For any reaction:

aA + bB ⇄ cC + dD

the equilibrium constant Kc is calculated as:

[tex]Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b}}[/tex]

In this case, you have:

2 ICl(g) → Cl₂(g) + I₂(g)

So, the equilibrium constant Kc is:

[tex]Kc=\frac{[Cl_{2} ]*[I_{2} ]}{[ICl]^{2} }[/tex]

Being:

Kc= 0.10[Cl₂]= ?[ICl]= 0.50 M[I₂]= 0.40 M

Replacing:

[tex]0.1=\frac{[Cl_{2} ]*0.40 M}{(0.50 M)^{2} }[/tex]

Solving:

[tex]0.1=\frac{[Cl_{2} ]*0.40 M}{0.25 M^{2} }[/tex]

0.1= 1.6 [tex]\frac{1}{M}[/tex]* [Cl₂]

[Cl₂]= 0.1 ÷ 1.6 [tex]\frac{1}{M}[/tex]

[Cl₂]= 0.0625 M

The equilibrium concentration of chlorine gas, Cl₂(g), is 0.0625 M

The equilibrium concentration of chlorine gas, if the equilibrium concentrations of ICl(g) and I₂(g) are known to be 0.50 M and 0.40 M respectively is 0.0625M.

How we calculate the equilibrium constant?

Equilibrium constant for any reaction will be define as the ratio of the concentration of products to the concentration of reactants with raise to their respective coefficients.

Given chemical reaction is:

2ICl(g) → Cl₂(g) + I₂(g)

Equilibrium constant for this reaction will be calculated as:

Kc = [Cl₂][I₂] / [ICl]², where

Kc = equilibrium constant = 0.10

[I₂] = concentration of iodine gas = 0.40 M

[ICl]² = concentration of ICl = 0.50 M = (0.50M)² = 0.25M²

[Cl₂] = concentration of chlorine gas = to find?

On putting all these values on the above equation and calculate for the value of [Cl₂] as follow:
[Cl₂] = Kc × [ICl]² / [I₂]

[Cl₂] = (0.10)(0.25) / (0.40)

[Cl₂] = 0.0625M

Hence, equilibrium concentration of chlorine gas is 0.0625M.

Answers

Answer:

Gravitational potential energy of water behind the dam

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Hydroelectric power plant refers to a renewable source of energy used for the generation of electricity, through the use of powerful hydraulic steam turbines operating at high voltage and are being driven by the energy acquired by water falling from a height and flowing through a penstock (pipe) i.e the mechanical energy (gravitational potential energy + kinetic energy).

A 20 ml of 0.27M of solution of the salt NaA has a pH of 8.70. Calculate the pKa value of the acid HA.

Answers

Answer:

pKa = 3.97

Explanation:

Let's state the equations:

NaA →  A⁻  +  Na⁺

A⁻ + H₂O  ⇄  OH⁻  +  HA    Kb

We don't have the concentration of [OH⁻] but we do know pH, so we can determine, pOH and after that, [OH⁻].

14 - pH = pOH → 14 - 8.70 = 5.30

10^-pOH = [OH⁻]  → 10⁻⁵'³⁰ = 5.01×10⁻⁶ M

Initially we can know, the moles of base, we had.

20 mL . 0.27M = 5.4 mmoles. So now, let's make the expression for Kb.

Kb = [OH⁻] . HA / [A⁻]

As the [OH⁻]  is so low, we can assume, there where no loses and the salt is well concentrated. So:

Kb = (5.01×10⁻⁶)² / 0.27 → 9.29×10⁻¹¹

Kw = Ka . Kb, then Ka = Kw/ Kb

Ka = 1×10⁻¹⁴ /9.29×10⁻¹¹ = 1.08×10⁻⁴

pKa = - log Ka → - log 1.08×10⁻⁴ = 3.97

Explanation: Maybe because there are four main tissue types in the body: epithelial, connective, muscle, and nervous. Each is designed for specific functions.

In chloroplast it is the structure within the cells of plants and green algae.

In stomach tissue has a thin simple columnar epithelial layer for secretion and absorption.

In bone tissue it is tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.

A 12.0 L balloon at 84 °C is cooled until it
becomes 5.0 L. To what temperature was
the balloon cooled?

Answers

Use Charles’ Law: V1/T1 = V2/T2. Given a mass of gas held at a constant pressure, changes in the gas’s temperature and volume are directly proportional. Since the volume of the gas in the balloon decreased, we should expect that the temperature had also decreased.

Here, V1 = 12.0 L, T1 = 357.15 K, and V2 = 5.0 L. To solve for T2, we rearrange the equation and compute:

T2 = V2T1/V1 = (5.0 L)(357.15 K)/(12.0 L)
T2 = 148.8125 K - 273.15 = -124.34 °C

To two significant figures, the answer would be -120 °C.

The ideal gas relates the volume, pressure, and temperature to each other. The balloon was cooled to -120 degrees celsius.

What is Charle's law?

Charle's law states the direct relationship between the volume and the temperature of the hypothetical gas. The law is given as,

[tex]\rm \dfrac{V_{1}}{T_{1}} = \rm \dfrac{V_{2}}{T_{2}}[/tex]

As it can be seen from the question the volume of the gas in the balloon is decreasing so the temperature will also decrease.

Given,

Initial volume = 12.0 L

Final volume = 5.0 L

Initial temperature = 357.15 K

The final temperature is calculated as:

[tex]\begin{aligned} \rm T_{2} &= \rm \dfrac{V_{2}T_{1}}{V_{1}}\\\\&= \dfrac{5\times 357.15}{12}\\\\&= 148.81\;\rm K\end{aligned}[/tex]

Therefore, -120 degrees celsius is the final temperature of the balloon.
