SUMMARY
The discussion centers on the necessity of multiplying the rate equation of a chemical reaction by the stoichiometric coefficients of reactants and products. This method ensures that the reaction rates are consistent across different substances involved in the reaction. For example, in the reaction 2AB → A2 + B2, the rate of AB decomposition is twice that of A2 formation, highlighting the importance of using coefficients to maintain a one-to-one rate comparison. This approach is not merely for convenience; it provides a clear framework for understanding the relationship between reactants and products in terms of their rates of consumption and production.
