What are the limitations of a chemical equation? How can these limitations be removed?

1. Chemical equation:

$\mathrm{Reactants}\to \mathrm{Products}$

In a balanced equation total number of atoms of an element on the reactants, side is equal to the total number of atoms of an element on the product side.

• Example:

$2\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2\mathrm{MgO}\left(\mathrm{s}\right)$

Magnesium Oxygen Magnesium oxide

2. Limitations of the chemical equation:

• In a chemical equation speed of the chemical equation is not mentioned.
• In a chemical equation time of completion is not mentioned.
• In a chemical equation concentration of reactants and products is not mentioned.
• In a chemical equation, temperature changes are not mentioned.

These limitations are not possible to remove for all reactions as we cannot write all this information for every reaction.

Also, the above limitations depend on the amount of reactants consumed and the amount of products formed which vary with need.
