The reason an increase in substrate concentration does not increase the reaction rate indefinitely is because
scoundrel [369]

Answer:

Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

A mixture of gaseous sulfur dioxide and oxygen are added to a reaction vessel and heated to 1000 K where they react to form SO3
nasty-shy [4]

Answer:

Kp = 0.0410

Explanation:

The reaction of gaseous sulfur dioxide and oxygen to form SO3 (g) is:

2SO₂(g) + O₂(g) ⇄ 2SO₃(g)

Kp is defined as the ratio of pressure of products and pressure of reactants:

Kp = \frac{P_{SO_3}^2}{P_{SO_2}^2P_{O_2}}

Kp = \frac{0.0851atm^2}{0.669atm^2*0.395atm}

Kp = 0.0410

I hope it helps!

What is the activity of a 52.3 μCi sample of carbon‑14 in becquerels?
Llana [10]

Answer:

1935100 Bq

Explanation:

Let us recall that:

If 1 μCi can be equivalent to 37000 Bq

Then; the activity of 52.3 μCi will be:

\dfrac{37000 \ Bq}{1 \ \mu Ci}\times 52.3 \ \mu Ci  \\ \\  \\ \\ \mathbf{= 1935100 \ Bq}

B. Lower elements have more energy levels

Explanation:

Ionization energy decreases down the group because lower elements have more energy levels. Therefore, the pull of the nucleus on the outermost shell electrons is not so great.

  • Ionization energy is the energy required to remove an electron from an atom.
  • It is a measure of the readiness of an atom to lose an electron.
  • Down a group or family, atomic radius increases due to addition of more electronic shells or energy levels.
  • As the atomic radius becomes larger, the ionization energy reduces.
  • This is because of the increased shielding/screening effect of inner shell electrons on the electron to be removed from the nuclear attraction.
  • This way, its takes a lesser amount of energy to remove them as shielding effects increases down the group.
