(B) The rate law for the reaction is given by: $\text{Rate} = k[N_2O_5]^n$. Assuming a first-order reaction with respect to $N_2O_5$ (as the unit of rate constant $s^{-1}$ indicates a first-order reaction),the rate law is $\text{Rate} = k[N_2O_5]$. Rearranging to find the concentration: $[N_2O_5] = \frac{\text{Rate}}{k}$. Substituting the given values: $[N_2O_5] = \frac{1.02 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}}{3.4 \times 10^{-5} \ s^{-1}} = 3 \ mol \ L^{-1}$.
