At what temperature will the rate constant for the reaction have the value 6.5×10−3 M/s?
(Assume k = 5.4 * 10^-4 M/s-1 at 599K and
k = 2.8 * 10^-2 M/s at 683K .)
You need to use the Arrhenius equation twice. The first time use it with the two k values given with the two T values and solve for Ea (activation energy), then use it the second time using Ea from the first calcn and either one of the K and T values to solve for T value for the desired k value in the problem.
Hey I tried that and still cant get the right answer. The answer that I got is 555.6 or 556 K and its not correct. What answer did you get?
I didn't do it. If you will post your work I will find the error.
