Chapter 16, Problem 88AE

Interpretation Introduction

Interpretation: The concentration of ${\text{K}}^{+}$ in muscle cells and blood plasma is given. Work done to transport $1.0\text{mol}$ of ${\text{K}}^{+}$ from blood to the inside of a muscle cell at a given temperature is to be calculated. It is to be identified that if any ion transported out when $1.0\text{mol}$ of ${\text{K}}^{+}$ is transferred inside. The reason is to be given for this transportation.

Concept introduction: The expression for free energy change at equilibrium is,

$\Delta G°=-RT\ln \left(K\right)$

If equilibrium concentration, $K$, is expressed in terms of concentration, then it is expressed as $X$.

$\Delta G°=-RT\ln \left(X\right)$
