The reaction 2N2O5 ---> 2N2O4 + O2 takes place at around room temperature in solvents such as CCl4 . The specific rate constant at 293 K is found to be 2.35 x 10^-4 s^-1 and at 303 K the specific rate constant is found to be 9.15 x 10^-4 s^-1. Calculate the frequency factor for the reaction at 303 K.
