Chapter 14, Problem 14.19P

(a)

Interpretation Introduction

Interpretation:

Value of standard cell potential and $K$ has to be calculated.

Concept Introduction:

Cell that is more negatively charged has better oxidation tendency and thus will readily lose electron. Electrons released from this electrode will reach positively charged reduction potential electrode.

Expression to compute $K$ from cell potential as per the Nernst equation as follows:

  $K={10}^{n(E_{\text{cell}}^{°})/0.05916}$

Here,

$K$ denotes equilibrium constant.

$E_{\text{cell}}^{°}$ denotes standard cell potential.

$n$ denotes moles of electrons transferred.

(b)

Interpretation Introduction

Interpretation:

Net cell voltage has to be calculated.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Direction of electron flow and whether $\text{Ag}\left(s\right)$ is oxidized or reduced has to be identified.

Concept Introduction:

Refer to part (a).
