Chapter 19, Problem 19.29QP

Interpretation Introduction

Interpretation:

The Zinc-carbon heavy-duty battery should be explained in terms of output.

Concept introduction:

Cell potential $\text{E}°$:

The electrochemical cell is a device, which is converting chemical energy into electrical current by chemical reaction within the cell.

If the chemical reaction within the cell is attains equilibrium means, the reaction will be stopped so the cell potential (EMF) will be zero, there is no electron flow in the external circuit, therefore the battery has dead.

If limiting reagent is more means the reaction occurs, when it will be completely reacted.
