प्रश्न
Chemical equations suffer from a number of limitations. State the main limitations of a chemical equation.
उत्तर
Limitations:
- Physical states of the reactants or products. But now we write along with substances (l) for liquids, (s) for solid, and (g) for gas.
- Conditions that affect the reaction, i.e. temp, pressure, or catalyst.
- Concentration of reactants and products we use dil. for dilute and cone, for concentrated.
- Nature of the chemical reaction.
- Speed – the reaction is fast or slow.
- Exothermic or endothermic we write + heat or – heat towards products for exothermic and endothermic.
- The completion of the reaction.
