The first-order rate constant for the decomposition of N2Os, given below, at 70C is 6.82 * 10-3 st Suppose we start with 0.0150 mol of N205(9) In a volume of 4.0 L. 2 N205(0) -- 4 NO2(g) + 026) (a) How many moles of NaOs will remain after 10 min? mol (b) How many minutes will it take for the quantity of Nz0s to drop to 0.005 mol? min (c) What is the half-life of N2Os at 70C? min
