In a series of experiments on the decomposition of dinitrogen pentoxide, N2O5, rate constants were determined at two different temperatures. At 35°C, the rate constant was 1.4×10-4/s; at 45°C, the rate constant was 5.0×10-4/s.

(a) What is the activation energy for this reaction?
(b) What is the value of the rate constant at 85°C?
