In your laboratory you're studying a chemical reaction that follows the general rate law: rate = k[A]. Initial experiments show a rate of 0.001412 M/s when [A] = 0.519 M at 299 K. You add a catalyst to the reaction, which is known to change the activation energy of the process by 1.5 kJ. What will the rate of the reaction be with the catalyst when [A] = 0.0757 M at 315 K? Assume that the Arrhenius factor for this reaction has been determined to be 0.673 s-1.
