Question

State any three limitations of a chemical equation.​

Answer 1

Answer:

Following are the limitations of a chemical equation:

(i) A chemical equation does not tell us the physical state of the reactants and the products in the reaction.

(ii) It does not tell us the actual concentration or dilution of the reactants used in the reaction.

(iii) It does not tell whether the reaction starts at its own or some heat is required to start the reaction.

(iv) It does not tell whether the reaction is violent in nature or not.

(v) The time taken by the reaction to complete itself is also not known.

Answer 2

Answer:

They do not provide information about: The physical state of reactants and products Hence, the symbols 's' for solid, 'l' for liquid, 'g' for gas and 'vap' for vapour are added. Conditions such as temperature, pressure and catalyst affecting the reaction.
