Calculate the frequency factor, A, for a reaction with a rate constant of 162.3 s^-1 and an activation energy, E_a, of 68 kJ mol^-1 at 298 K.

Question

Quizplus · Accepted Answer

The frequency factor, A, can be calculated using the Arrhenius equation: k = A * e^(-Ea/RT). Rearranging for A gives A = k / e^(-Ea/RT). Substituting the given values (k = 162.3 s^-1, Ea = 68,000 J/mol, R = 8.314 J/mol·K, T = 298 K) results in A ≈ 1.3 × 10^14 s^-1.
