The first-order rate constant for the decomposition of N2O5, given below, at 70'C is 6.82 X 107. Suppose we start with 0.0300 mol of NOso) in a volume 3.5 L 2. NO.() -- 4 NO (0) + (0) (a) How many moles of N,Os will remain after 10 min? 0175 X mol (b) How many minutes will it take for the quantity of N20, to drop to 0.005 mol? X min 3.0 () What is the half-life of N Os at 70C 1.7 min
