Activation Energy Calculator
Determine Activation Energy ($E_a$) using the two-point Arrhenius Equation
Formula: $E_a = \frac{R \cdot \ln(k_2 / k_1)}{\frac{1}{T_1} - \frac{1}{T_2}}$
Where Universal Gas Constant ($R$) = 8.314 J/(mol·K).
Where Universal Gas Constant ($R$) = 8.314 J/(mol·K).

⚠️ Note: The Arrhenius equation assumes that Activation Energy ($E_a$) and the pre-exponential factor ($A$) remain constant over the given temperature range. Extremely large temperature differences may introduce discrepancies in real-world kinetics.
