Answer: When the reaction reaches equilibrium, the cell potential will be 0.00 V

Explanation:

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.

The standard emf of a cell is related to Gibbs free energy by following relation:

$\Delta G=-nFE^0$

The Gibbs free energy is related to equilibrium constant by following relation:

$\Delta G=-2.303RTlog K$

For equilibrium $\Delta G=0$

Thus $0=-nFE^0$

$E^0=0$

Thus When the reaction reaches equilibrium, the cell potential will be 0.00 V

Due to decay of ⁴⁰K, cow’s milk has a specific activity of about 6X10⁻¹¹mCi per milliliter. How many disintegrations of ⁴⁰K nucl

FromTheMoon [43]

When we discuss radioactive isotope activity, we consider how many decays or disintegrations occur per unit of time. Therefore, activity is determined by the quantity of disintegrations over time. Ah, the becquerel, or B que, is a measurement unit that is widely used to quantify activity. It is equivalent to one decay or one disintegration per second. Therefore, we occasionally shorten it to one d. per s. The curie, denoted by the letters C I, is a second unit we used to denote activity. The result is 1.4 times 10 to the negative 11. Curie's modify this to Beck, Carell's One Curie from curies. His 10 times 10 times 3.7 's Becca Rell And we are aware that one Decorah is equal to one Decay every second. Therefore, we multiply by 1.4 x 10 - 11 times. There are 5 to 5 decays per second, or 3.7 x 10 to the 10 refined. There is one more conversion because my query now asks us what this would be in decays per minute. We multiply 60 by 5.5 to 5 to get the number of decays per minute from our activity and decays per second. This yields 32 decays per minute, which is significant at 30.

<h3>What are isotopes?</h3>

Isotopes are two or more atom types that have the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a particular element are almost identical, they differ in their atomic weights and physical characteristics.
