The initial rate method in chemical kinetics is justified because it allows for accurate measurements of reaction rates before significant changes in reactant concentrations occur. This method captures the linearity of the rate at the beginning of the reaction, ensuring that data reflects the true kinetics without interference from product formation or concentration shifts. Waiting longer to measure rates can lead to inaccuracies due to these changes, making initial rates a reliable approach for kinetic analysis.
