Chapter 21.3, Problem 1PE

Interpretation Introduction

Interpretation: The electrochemical potential created by the unequal concentrations of ${\text{K}}^{\text{+}}$ inside a frog muscle cell and work done to transport ${\text{K}}^{\text{+}}$ into the cell at $\text{310}\text{K}$ is to be calculated.

Concept introduction: Solutions with two different concentrations separated by a membrane constitute a concentration cell. Free energy ( $\Delta G$) represents the work involved in a thermodynamic process, such as transporting an ion across a cell membrane.

To determine: The electrochemical potential created by the unequal concentrations of ${\text{K}}^{\text{+}}$ in a frog muscle cell and work done to transport ${\text{K}}^{\text{+}}$ into the cell at $\text{310}\text{K}$.
