The equilibrium conversion ratio will be 5.

To solve this problem, we need to use the equilibrium constant expression for the reaction:

C2H4 + H2O ⇌ C2H5OH

K = [C2H5OH]/([C2H4][H2O])

At equilibrium, the reaction quotient Qc will be equal to the equilibrium constant K:

Qc = [C2H5OH]/([C2H4][H2O]) = K

We can express the concentrations of the reactants and products in terms of the conversion x:

[C2H4] = (1 - x)/6

[H2O] = (5 - x)/6

[C2H5OH] = x/6

Substituting these expressions into the equilibrium constant expression and simplifying, we get:

K = x/[(1 - x)(5 - x)]

At 523.15 K and 35 bar, the equilibrium constant K can be calculated using the Van't Hoff equation:

ln(K2/K1) = ΔH°/R × (1/T1 - 1/T2)

where K1 is the equilibrium constant at a reference temperature T1, K2 is the equilibrium constant at the temperature of interest T2, ΔH° is the standard enthalpy change for the reaction, and R is the gas constant.

Assuming that ΔH° is constant over the temperature range of interest, we can integrate the above equation to obtain:

ln(K2) = ln(K1) - ΔH°/R × (1/T2 - 1/T1)

At 298.15 K, the standard enthalpy change for the reaction is ΔH° = -137.2 kJ/mol. Using the given fugacity coefficients, we can calculate the equilibrium constant K1 at 298.15 K and 1 bar:

K1 = ([C2H5OH]/([C2H4][H2O]))1 bar = (0.827/0.977)/(0.16 × 0.887) = 11.48

Substituting the given temperature and pressure into the Van't Hoff equation, we get:

ln(K) = ln(K1) - ΔH°/R × (1/523.15 - 1/298.15) + ln(35/1)

Solving for ln(K) and taking the exponential of both sides, we get:

K = 128.7

Substituting this value of K into the equilibrium constant expression, we get:

128.7 = x/[(1 - x)(5 - x)]

Solving for x, we get:

x = 0.535

Therefore, the equilibrium conversion of ethylene to ethanol is 53.5% at 523.15 K and 35 bar for an initial steam-to-ethylene ratio of 5.

Gamma radiation is the most penetrating. It can penetrate air, paper or thin metal. It may only be stopped by many centimetres of lead or many metres of concrete.

A solution at pH 1 has more hydrogen ions than a solution at pH 4. The pH of a solution refers to the hydrogen ion concentration.

The concentration of hydrogen ions and the pH of a solution are inversely proportional. This means that the higher the hydrogen ion concentration, the lower the pH, and vice versa.

A solution at pH 1 will have more hydrogen ions than a solution at pH 4.The pH of a solution is defined as the negative logarithm of the hydrogen ion concentration. The equation for calculating the pH of a solution is given as follows:

\($$pH = -\log_{10}[H^+]$$\)

In this equation, [H⁺] is the hydrogen ion concentration in moles per liter (mol/L) of solution. A change of 1 pH unit corresponds to a 10-fold change in the hydrogen ion concentration.

Therefore, if a solution has a pH of 1, it has a hydrogen ion concentration of 0.1 mol/L.

If a solution has a pH of 4, it has a hydrogen ion concentration of 0.0001 mol/L. Thus, a solution at pH 1 has more hydrogen ions than a solution at pH 4.

If you haven't checked your tire pressure since August and it is now winter, you would likely expect your tire pressure to be lower than it was in August.

When it comes to tire pressure, there are a few factors that can affect it. Temperature, for example, can have a significant impact on tire pressure. In general, as temperatures decrease, tire pressure will also decrease. This is because the air inside the tire contracts in colder temperatures, resulting in a decrease in pressure.
However, there are also other factors that can affect tire pressure, such as the type of tire you have and how often you use your vehicle. If you have high-performance tires, they may be designed to maintain a higher pressure regardless of temperature changes. Additionally, if you use your vehicle frequently, you may be able to maintain a consistent tire pressure regardless of the season.
In any case, it is always a good idea to check your tire pressure regularly, especially during the winter months. Proper tire pressure is essential for safe and efficient driving, as it can affect everything from fuel economy to handling and braking performance. So, if you haven't checked your tire pressure in a while, it's best to do so as soon as possible to ensure that you're driving with optimal pressure levels.

The reaction of ∆G° is -14,736 J. A negative ∆G° indicates that the reaction can proceed spontaneously without the input of external energy.

To calculate ∆G° (standard Gibbs free energy change) for a reaction, we can use the equation:

∆G° = ∆H° - T∆S°

Given:

∆H° = 24.6 kJ

∆S° = 132 J/K

T = 298 K

First, we need to convert the units of ∆H° to match the units of ∆S° (kJ to J):

∆H° = 24.6 kJ = 24,600 J

Now, we can substitute the values into the equation to calculate ∆G°:

∆G° = 24,600 J - (298 K) * (132 J/K)

∆G° = 24,600 J - 39,336 J

∆G° = -14,736 J

Since ∆G° is negative (-14,736 J), the reaction is spontaneous under these conditions. A negative ∆G° indicates that the reaction can proceed spontaneously.

Ge has an ionization energy that is different than you would predict based off ENC values.

Ionization enthalpy, which is used to turn an isolated gaseous atom into a gaseous cation, is the minimal amount of energy needed to remove the loosestly bonded electron.

Electron volts (eV) per atom, kilocalories per mole, or kilojoules per mole are used as units of measurement. Both the force of attraction between electrons and the nucleus and the force of repulsion between electrons are factors affecting I.E.

In an electric discharge tube, where a fast-moving electron produced by an electric current collides with a gaseous atom of the element, causing it to eject one of its electrons, the ionization energy of a chemical element, expressed in joules or electron volts, is typically measured.

The percent by mass of each compound in the mixture is 24.04% NaBr and 75.96% Na₂SO₄.

Percentage by mass, mass %, is a measure of concentration that indicates the mass of solute per mass of solution. In other words, the mass percent of a component in the solution is defined as the ratio of the mass of the component to the mass of the solution, expressed as a percentage.

mass % = (mass of solute / mass of solution) x 100

In the case of a mixture of NaBr and Na₂SO₄ that contains 29.96% Na by mass, assume 100 g of the mixture.

Let x = mass of NaBr

100 - x = mass of Na₂SO₄

29.96 g = mass of Na in NaBr + mass of Na in Na₂SO₄

29.96 g = (mass of NaBr)(mass % Na in NaBr/100) + (mass of Na₂SO₄)(mass % Na in Na₂SO₄/100)

29.96 g = (x)(22.989769/102.893769) + (100 - x)(2 · 22.989769/142.040538)

29.96 g = 0.2234320817x + (100 - x)(0.3237071518)

29.96 g = 0.2234320817x + 32.37071518 - 0.3237071518x

0.3237071518x - 0.2234320817x = 32.37071518 - 29.96

x = 24.04102213

100 - x = 100 - 24.04102213 = 75.95897787

mass % NaBr = (mass of NaBr / mass of mixture) x 100

mass % NaBr = (24.04102213 / 100) x 100

mass % NaBr = 24.04102213

mass % Na₂SO₄ = (mass of Na₂SO₄ / mass of mixture) x 100

mass % Na₂SO₄ = (75.95897787 / 100) x 100
