Limitations of chemical equations


The chemical reactions suffer from a number of limitations and thus have a few drawbacks also.
1. The physical states of the reactants and products.
2. The concentration of the reactants and products.
3. The conditions such as temperature, pressure or catalyst etc which affect the reaction.
4. The heat changes accompanying the reaction i.e. whether heat is evolved or absorbed during the reaction.
5. The formation of a precipitation or the evolution of gas in the reaction.
6. The speed of the reaction.
7. The nature of the reaction i.e. whether the chemical reaction is reversible or irreversible.
