Solved: The gas-phase decomposition of peroxyacetyl
Chapter 20, Problem 58P(choose chapter or problem)
The gas-phase decomposition of peroxyacetyl nitrate (PAN) obeys first-order kinetics:
\(\mathrm{CH}_3\mathrm{COOONO}_2\ \longrightarrow\mathrm{\ CH}_3\mathrm{COOO}+\mathrm{NO}_2\)
with a rate constant of \(4.9\times10^{-4}\mathrm{\ s}^{-1}\). Calculate the rate of decomposition in M/s if the concentration of PAN is 0.55 ppm by volume. Assume STP conditions.
