Given the following data for the reaction A $\to$ B,determine the frequency factor,A,of the reaction.

Question

Quizplus · Accepted Answer

To determine the frequency factor, we need to use the Arrhenius equation: k=Ae^(-Ea/RT), where k is the rate constant, A is the frequency factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin. We can rearrange the equation to solve for A: A=k/e^(-Ea/RT). Since we are given the rate constant k and the temperature, we can plug them in to solve for A. A = k / e^(-Ea/RT) = 0.00295 / e^(128000/(8.31*298)) = 0.306 (rounded to three significant figures). Therefore, the best choice is A.
