Which of the following statements is predicted to be false?

Chemistry
1 answer:
Paul [167]3 years ago
6 0

Answer:

(c) an aqueous solution of CO2 exhibits dipole-dipole forces between solute and solvent

Explanation:

Co2 is a non-polar molecule.

It is actually shown to be O=C=O.

When dissolved in water to get aqueous solution.

Dipole on water molecule can induce dipole on CO2.

This entails that we should have dipole-induced dipole forces when we have a mixture or solvent and solute.

But the given statement states dipole dipole forces between solute and solvent.

Hence the statement is false.

An inhibitor is added to an enzyme-catalyzed reaction at a concentration of 26.7 μM. The Vmax remains constant at 50.0 μM/s, but
fomenos

Using the Michaelis-Menten equation competitive inhibition, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

<h3>What is the Ki for the inhibitor?</h3>

The Ki of an inhibitor is known as the inhibition constant.

The inhibition is a competitive inhibition as the Vmax is unchanged but Km changes.

Using the Michaelis-Menten equation for inhibition:

  • Kma = Km/(1 + [I]/Ki)

Making Ki subject of the formula:

  • Ki = [I]/{(Kma/Km) - 1}

where:

  • Kma is the apparent Km due to inhibitor
  • Km is the Km of the enzyme-catalyzed reaction
  • [I] is the concentration of the inhibitor

Solving for Ki:

where

[I] = 26.7 μM

Km = 1.0

Kma = (150% × 1 ) + 1 = 2.5

Ki = 26.7 μM/{(2.5/1) - 1)

Ki = 53.4 μM

Therefore, the Inhibition constant, Ki of the inhibitor is 53.4 μM.
