Calculate the activation energy, E_a, for a reaction with a frequency factor, A, of 6.10 × 10¹⁴ s^-1 and a rate constant of 13.0 s^-1 at 320 K.

Question

Quizplus · Accepted Answer

The activation energy can be calculated using the Arrhenius equation: k = A * e^(-Ea/RT). Rearranging for Ea gives Ea = -RT ln(k/A). Substituting the given values (R = 8.314 J/mol·K, T = 320 K, k = 13.0 s^-1, A = 6.10 × 10^14 s^-1) results in Ea ≈ 83.8 kJ/mol.
