a) If the observed rate constant for the oxidation reaction at 35 C is 6.75*10^-2 min^-1, and at 25 C is 3.25*10^-2 min ^-1. what is the activation energy for the reaction?
b) What is the rate constant for the previous reaction at 45 C.
c) If the initial concentration of dichromate ion in part @ at 25 C is 1.50*10^-1 M, what will be the concentration of dichromate at 30.0 min.
