The first-order rate constant for the decomposition of N2O5,
2N2O5(g)→4NO2(g)+O2(g)
at 70∘C is 6.82×10−3 s−1. Suppose we start with 2.80×10−2 mol of N2O5(g) in a volume of 2.2 L .
How many moles of N2O5 will remain after 6.0 min ?
How many minutes will it take for the quantity of N2O5 to drop to 1.6×10−2 mol ?
What is the half-life of N2O5 at 70∘C?
