Question

Chemical equations suffer from a number of limitations. State the main limitations of a chemical equation.

Answer 1

Limitations:

1. Physical states of the reactants or products. But now we write along with substances (l) for liquids, (s) for solid, and (g) for gas.
2. Conditions that affect the reaction, i.e. temp, pressure, or catalyst.
3. Concentration of reactants and products we use dil. for dilute and cone, for concentrated.
4. Nature of the chemical reaction.
5. Speed – the reaction is fast or slow.
6. Exothermic or endothermic we write + heat or – heat towards products for exothermic and endothermic.
7. The completion of the reaction.
