The reaction 2N2O5(g) ----- O2(g) + 4NO2(g). is first order in N2O5. For this reaction at 45oC, the rate constant k = 1.0 × 10^–5 s–1. For a particular experiment ([N2O5]0 = 1.0 × 10^–3 M), calculate [N2O5] after 2.6 × 10^5 seconds. A 1.0 x 10^-3 M B 7.4 x 10^-5M C 2.6M D 9.5M E none of these is correct
