Question

Quizplus · Accepted Answer

The balanced equation for the cell reaction is:
ZnS1U1P12 + 2 AgS1U1P1+ → ZnS1U1P11 + 2 AgS1S1P0

The expression for the reaction quotient, Q, is given by:
Q = [ZnS1U1P12]/[AgS1U1P1+]2

Substituting the given concentrations, we get:
Q = [0.0110]/(1.27)2
Q ≈ 6.82 × 10S1U1P1-3S1S1P0

Therefore, the answer is B.
