Option B is correct

K = Kp /Kr

The given equation indicating, the product containing 6 moles of proton whereas the reactant contains 2 mole of bismuth and 3 mole of hydrogen sulphide.

Hence, in reaction B there are 2 mole of bismuth and 3 mole of hydrogen sulphide reacting to produce 6 moles of proton. whereas the concentration of Bi2S3 is not considered as it is present in solid phase.

Answer:

2Bi2+(aq) + 3H2S(aq)↔ Bi2S3(s) + 6H+(aq)

Explanation:

In general for a hypothetical reaction:

x(Reactants) ↔ y(Products)

the equilibrium constant, Keq is given by the ratio of the products to that of the reactants raised to the appropriate coefficients.

Keq = \frac{[Products]^{y} }{[Reactants]^{x} }

The given Keq is:

Keq = \frac{[H+]^{6}}{[Bi2+]^{2} [H2S]^{3} }

This implies that the reactants are: H2S (aq) and Bi2+(aq)

Products are: H+(aq)

Therefore the reaction with the appropriate coefficients would be:

2Bi2+(aq) + 3H2S(aq)↔ Bi2S3(s) + 6H+(aq)

Since the activity of solids = 1, Bi2S3 is not included in Keq

There should be a sufficient amount of the selected isotope in the rock.

The half-life of the isotope must be long enough to capture the age of the rock.

Explanation:

Sully must consider two main aspect before selecting her choice isotope for dating.

There must be sufficient amount of the selected isotope in the rock.

The half - life of the isotope must be long enough to capture the age of the rock.

  • Radiometric dating gives a rock an absolute numerical age.
  • The half-life of an isotope is time take for half of a radioactive element to decay.
  • If the half-life of an isotope is very short, all the parent nuclide would have turned to daughter nuclides.
  • Also, we must have sufficient amount of both the daughter and parent isotope in the selected rock.
