At body temperature (37°C), the rate constant of an enzymecatalyzed decomposition is 2.3X10¹⁴ times that of the uncatalyzed reac
schepotkina [342]

The activation energy is lowered by 85351.23 J/mol.

<h3>What is the activation energy?</h3>

The activation energy is the energy that is used to start a reaction.

In K = (In A) - (Ea / RT)

In K = (-Ea / RT) + In A

Where k = the activity constant

Ea = activation energy

R = molar gas constant

T = absolute temperature in Kelvin

In K₁ = (-Ea₁ / RT) + In A (eqn 1)

At point 2 with the catalyst

In K₂ = (-Ea₂ / RT) + In A (eqn 2)

Note that the molar gas constant, the absolute temperature in Kelvin, and the activity constant are all the same for both points.

Subtract (eqn 1) from (eqn 2)

In K₂ - In K₁ = (-Ea₂ / RT) - (-Ea₁ / RT) + In A - In A

In (K₂ / K₁) = (1/RT) (Ea₁ - Ea₂)

We were told that K₂ / K₁ = 2.3 × 10¹⁴, then find the difference in Ea

R = 8.314 J/mol.K, T = 37°C = 310.15 K

In (2.3 × 10¹⁴) = (1/ (8.314×310.15) (Ea₁ - Ea₂)

33.1 = (1/2578.5871) (Ea₁ - Ea₂)

(Ea₁ - Ea₂) = 33.1 × 2578.5871 = 85351.23 J/mol

Thus, the enzyme that lower the Ea is 85351.23 J/mol.

What is the perecentage yield of a reaction in which 200g PCl3 reacts with excess water to form 128g HCl according to the f.F re
castortr0y [4]

Answer:

The percentage yield is 80.36% (see calculations in attachment).

Explanation:

The theoretical  yield of the reaction is the <u>amount of product that would result if all the  limiting reagent reacted.</u> The theoretical yield is calculated using the balanced equation.

In practice, the actual yield, or the <u>amount of  product actually obtained from a reaction</u>, is almost always less than the theoretical  yield.

To determine how efficient this reaction is, we need to calculate the percent  yield, which describes the <u>proportion of the actual yield to the theoretical yield.</u> It is  calculated as follows:

%yield = actual yield ÷ theoretical yield × 100%

First we need to make sure that the equation is properly balanced. In the question they provide the balanced equation.

Since water is in excess, we calculate the theoretical yield using PCl₃.

sergeinik [125]

Answer:

Electrones de valencia.

Explanation:

¡Hola!

En este caso, dado en química se conocen las estructuras de Lewis como representaciones gráficas de como los elementos están enlazados entre sí, debemos tener en cuenta que estos enlaces se forman entre los electrones de valenciam, los cuales son utilizados para su representación. Se sabe que los electrones de valencia son representados con puntos alrededor del elemento a través de puntos que se unen entre sí y son el número de electrons en la capa más externa de los elementos en cuestión; por ejemplo, cloro tiene 7 electrones de valencia, azufre tiene 6, hidrogeno 1, carbono 4 y así sucesivamente.

¡Saludos!
