The reaction is enabled when there is an external path for electric current and ceases when that path is broken. Being that the motivation for electrons to move through a cell is chemical in nature, the amount of voltage (electromotive force) generated by any cell will be specific to the particular chemical reaction for that cell type.
Chemical Equations. A chemical equation is a written expression of a chemical reaction; e.g., \[2 H_2 + O_2 \rightarrow 2 H_2O \label{eq}\] Reactants are written on the left, and products are written on the right. In a balanced equation the total numbers of atoms of each kind on both sides are the same.

1. Direct Union or Combination Reactions Any reaction in which two or more substances combine to form a single product is a direct union or combination reaction. The general form of a direct union reaction is A + B → AB This type of reaction generally takes place between the following types of compounds: a. A metal + non-metal
3) A(n) exothermic reaction is one where the products have lower energy than the reactants. 4) Endothermic reactions require energy in order to take place. 5) Spontaneous changes take place by themselves, without any help. 6) The enthalpy change (ΔH) is used to describe how much energy is produced or used during a chemical change.

Rates of reaction. Suppose we start a chemical reaction and record how much product is made over time. Unless something very strange happens, the graph will look like this: The first part of the graph is a straight line - this is also the time when the reaction is fastest. As time passes, the reaction starts to go more slowly, then it stops.
