The first-order rate constant for the decomposition of N2O5,
2N2O5(g)?4NO2(g)+O2(g),
at 70?C is 6.82�10?3s?1. Suppose we start with 3.00�10?2mol of N2O5(g) in a volume of 2.5L .
A) How many moles of N2O5 will remain after 7.0min ?
Express your answer using two significant figures.
B) How many minutes will it take for the quantity of N2O5 to drop to 1.1�10?2mol ?
Express your answer using two significant figures.
C) What is the half-life of N2O5 at 70?C?
