For the decomposition of gaseous dinitrogen pentoxide (shownbelow),
2 N2O5(g).....> 4NO2(g) + O2(g)
the rate constant is k = 2.8 10-3 s-1 at 60°C. The initial concentration of N2O5 is 1.52 mol/L.
(a) What is [N2O5] after 5.00 min?
_____mol/L
(b) What fraction of the N2O5 has decomposed after 5.00 min?
