What are the limitations of a chemical equation ?
उत्तर
- It does not inform about the physical states of the reactants and the product i.e. whether they are solids, liquids and gases.
- It does not inform about the concentration of reactants and products.
- It does not inform about the time taken for the completion of the reaction.
- It does not inform about the rate at which a reaction proceeds.
- It does not inform about the heat changes during the reaction i. e. whether the heat is given out or absorbed.
- It does not inform about the conditions such as temperature, pressure, catalyst etc. which affect the reaction.
