The decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30

The decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30 °C

N₂O₅2 NO₂ + ½ O₂

is first order in N₂O₅ with a rate constant of 4.10E-3min^-1.

If the initial concentration of N₂O₅ is 1.31 M, the concentration of N₂O₅ will be M after 324min have passed.
