The rate constant for the reaction A -> B is 25 min^-1 at 298 K and 35 min^-1 at 350 K. Calculate the value of the rate constant at 770 K. Give your answer in min^-1.

How do you approach this problem?

Use the Arrhenius equation
("to predict the value of a rate constant at one temperature from its value at another temperature.")
(Textbook pg. 642.)
