Calculate the value of the reaction quotient,Q,for the galvanic cell expressed using shorthand notation below.Use the balanced chemical equation that has the smallest whole number stoichiometric coefficients.
Zn(s) ∣ Zn²⁺(aq,0.0100 M) ∣∣ Ag⁺(aq,1.15 M) ∣ Ag(s)

Question

Quizplus · Accepted Answer

The balanced chemical equation for the cell reaction is:

Zn(s) + Ag+(aq) → Zn2+(aq) + Ag(s)

The cell notation shows that the concentrations of the species involved in the reaction are:

[Zn2+] = 0.0100 M (in the left half-cell)
[Ag+] = 1.15 M (in the right half-cell)

The reaction quotient, Q, is given by the formula:

Q = [Zn2+]/[Ag+]

Substituting the values, we get:

Q = 0.0100 M / 1.15 M
Q = 8.70 × 10^-3

Therefore, the best choice is D, 7.56 × 10^-3.
