Activation energiy is te minimum appligt of energiy applicd for a chemical reaction to occur. Determining this energiy using experimental data complives analyzing reaction rates at different temperature. This process helps understand thee reaction 's kinetics and can bee useful in various scientific and industrial applications.

Collecting Experimental Data

Begin by measuring te reaction rate at multiple temperature. Use consistent conditions for each measurement, varying only the temperature. Record thee rate constants (k) corresponding to each temperature (T). Accurate data collection is essential for reliable calculations.

Appliying thee Arrhenius Equation

Te Arrhenius equation relates the rate constant to temperature and activation energiy:
