a) A species undergoes a first-order reaction with a half-life of 36.7 s. If the initial concentration of this species is 2.00 M, how long does it take for the concentration of the species to decrease to 0.200 M? b- The decomposition of N2O5 at 20.0 ºC (293.15 K) has a rate constant of 2.0 × 10-5 s-1. If the frequency factor (A) for this reaction is 5.8 × 1012 s-1. Calculate the activation energy (Ea) of this reaction in kJ mol-1
