The first-order rate constant for the decomposition of N2O5, 2N2O5 --> 4NO2 + O2 at 70 degrees C is 6.82 * 10 ^-3 . Suppose we start with 2.90×10?2 of in a volume of 1.7 L. A) How many minutes will it take for the quantity of N2O5 to drop to 1.3 * 10^-2 moles B) What is the half life of N2O5 at 70 C
