Which is not true of the standard conditions for electrochemical cell measurements?

SAT
1 answer:
Basile [38]2 years ago
7 0

In thermodynamics, the pressure is taken in the atm unit. Gases are at 1 bar pressure, then the incorrect option is A.

<h3>What is an electrochemical cell?</h3>

An electrochemical cell is a device that may either create electrical energy from chemical processes taking place inside it or use electrical energy given to it to promote chemical reactions taking place inside it.

In chemistry, standard pressure is usually measured in the atm rather than the bar. For electrochemical cell measurements, the standard conditions are as follows:

Gases must be at a pressure of 1 atm.

Pure liquids are required.

Solids must also be in their purest form.

The concentration of solutes is 1.0 M.

And the voltages in the cells are positive.

More about the electrochemical cell link is given below.

Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction.
Klio2033 [76]

According to the research, the statement "Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction" is true.

<h3>What are dipole-dipole attractions?</h3>

It is observed between a positive dipole of a polar molecule with the negative dipole of another, the atom with the highest electronegativity attracts electrons towards itself, forming a negative dipole around it.

In polar covalent bonds, the atom with the least electronegativity, the dipole formed has a positive charge, since it partially gives up its electrons.

Therefore, we can conclude that according to the research, the statement "Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction" is true.

Aleonysh [2.5K]

<u>The equilibrium rate of return on a 1 year T-bond is 5%</u>

<u />

<h3>Equilibrium rate</h3>

This is the interest rate at which the demand meet the supply at a particular point.

<h3>Equilibrium rate of return</h3>

This is the sum of dividend yield plus the rate of capital gains.

we can also say that the equilibrium rate for a 1 year T-bond in this case is the sum of the real risk free rate and the expected inflation.

Data

  • Real risk free rate = 3%
  • Expected inflation = 2%

Hence, the equilibrium rate of return will be 3% + 2% = 5%.

From the above, the equilibrium rate of return is 5%
