A particular first-order reaction has a rate constant of 1.35 × 10² s^-1 at 25.0 °C. What is the magnitude of k at 65.0 °C if E_a = 55.5 kJ/mol?

Question

Quizplus · Accepted Answer

The Arrhenius equation is used to calculate the rate constant at a different temperature: k = A * exp(-Ea/(RT)). Using the given Ea and temperatures, the rate constant at 65.0 °C is calculated to be approximately 1.92 × 10^3 s^-1.
