A reaction rate increases by a factor of 655 in the presence of a catalyst at 37°C. The activation energy of the original pathway is 106 kJ/mol. What is the activation energy of the new pathway, all other factors being equal? Group of answer choices 89.3 kJ/mol 16,600 kJ/mol 89.3 J/mol 16,600 J/mol

Answers

For a reaction rate that increases by a factor of 655 in the presence of a catalyst at 37°C, the activation energy of the new pathway  is mathematically given as

Ea2=89.28JKoule/mol

What is the activation energy of the new pathway, all other factors being equal?

Generally, the equation for the rate constant  is mathematically given as

K=Ae^{Ea1/Rt}

Therefore

[tex]\frac{1}{655}=\frac{1}{8.31*3.10}(Ea2-105000)[/tex]

Ea2=89286.083Joule/mol

In conclusion, the activation energy

why is it necessary to standardize a secondary standard before use?

Answers

Answer:

As the name implies, a secondary standard is used by standard laboratories, which include companies involved in the preparation of reagents and kits, as well as laboratories responsible to produce quality control material for use by other laboratories. They use the primary standard as the primary calibrator or primary reference material, and they calibrate their instruments against it. Smaller labs use secondary standards to calibrate control material for analysis of unknown concentrations. For smaller labs, secondary standard serves as an external quality control. As a result, it is essential that the secondary standard be standardized against the primary standard before it can be applied.

If 4.65 LL of CO2CO2 gas at 22 ∘C∘C at 793 mmHg mmHg is used, what is the final volume, in liters, of the gas at 35 ∘C∘C and a pressure of 743 mmHg mmHg , if the amount of CO2CO2 does not change?

Answers

Answer:

About 7.9 L.

Explanation:

We can utilize the ideal gas law. Recall that:

[tex]\displaystyle PV = nRT[/tex]

Because the amount of carbon dioxide does not change, we can rearrange to formula to:
[tex]\displaystyle \frac{PV}{T}= nR[/tex]

Because the right-hand side stays constant, we have that:
[tex]\displaystyle \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} = nR[/tex]

Hence substitute initial values and known final values:
[tex]\displaystyle \begin{aligned} \frac{(793\text{ mm Hg})(4.65 \text{ L})}{(22 \text{ $^\circ$C})} & = \frac{(743 \text{ mm Hg})V_2}{(35\text{ $^\circ$C})} \\ \\ V_2 & = 7.9\text{ L}\end{aligned}[/tex]

Therefore, the final volume is about 7.9 L.

What volume of .15M NaOH could be produced with only 5 grams of NaOH and water?

Answers

The volume of 0.15M NaOH that could be produced with only 5 grams of NaOH and water is 0.83L.

How to calculate volume?

The volume of a substance can be calculated using the following expression:

Molarity = number of moles ÷ volume

The number of moles of NaOH can be calculated by dividing the mass of NaOH by its molar mass.

Molar mass of NaOH = 40g/mol

n = 5/40

n = 0.125moles

Volume of NaOH = 0.125mol ÷ 0.15M

Volume = 0.83L

Therefore, the volume of 0.15M NaOH that could be produced with only 5 grams of NaOH and water is 0.83L.

Given the molecular formula of aspirin, C₉H₈O₄, in 1.50 moles of aspirin there are 13.5 moles of carbon.

What is a mole?

The mole is the SI base unit for the amount of matter. 1 mole of particles contains a number of Avogadro's particles.

We have 1.50 moles of aspirin, C₉H₈O₄. According to the molecular formula, the molar ratio of C₉H₈O₄ to C is 1:9.

1.50 mol C₉H₈O₄ × (9 mol C/1 mol C₉H₈O₄) = 13.5 mol C

Scientists observe that over the span of 100 years, the proportion of the population with long tails increases from 10% to 60%. Which statement is most likely? (1 point)

The proportion of long-tailed squirrels may have increased due to a decrease in trees.

The proportion of short-tailed squirrels may have decreased due to an increase in trees.

The proportion of short-tailed squirrels may have decreased due to decreased food availability.

The proportion of long-tailed squirrels may have increased due to increased food availability.

Answers

The proportion of long-tailed squirrels may have increased due to increased food availability.


The statement has it that the percentage of long tailed increased also that the long tailed are better at jumping and balancing on trees.

The first option could is tempting but saying decrease in trees would not likely support the argument.

The last option has more sound options as more food availability may lead to population increment

Find the acceleration of the 2 kg block in the following diagram. ( Hint find the net force!)​

Answers

Answer:
2m/s^2
Explanation:
Fnet = F2-F1
ma = 8-4
2a = 4
Dividing both sides by 2
a = 2
Therefore (a) thus acceleration is 2m/s^2

The acceleration of the block will be -2 m/s² in the backward direction.

What is force?

Force is defined as the product of mass of the body and the acceleration with which it is moving. Mathematically -

F = ma

It is a vector quantity. In the three dimensional coordinate system, the force vector can be resolved as -

[F] = F[x] a[x] + F[y] a[y] + F[z] a[z]

Given is a diagram in which two forces are acting on a block.

We can write -

Force 1 on block [F1] = 4 a[x]

Force 2 on block [F2] = 8 (- a[x]) = - 8 a[x]

Resultant of forces [F] = [F1] + [F2] = 4 a[x] + ( - 8 a[x]) = - 4 a[x]

Now, we know that -

F = MA

A = F/M

In vector form, acceleration will be -

[A] = - 1/m × (4 a[x])

[A] = -1/2 × (4 a[x])

[A] = - 2 a[x]

Therefore, the acceleration of the block will be -2 m/s² in the backward direction.
