At elevated temperatures, dinitrogen pentoxide decomposes to nitrogen dioxide and oxygen: 2N2O5(g)→4NO2(g)+O2(g) Part A When the rate of formation of O2 is 8.5×10−3 M/s, the rate of decomposition of N2O5 is M/s.

Rate of disappearance of N₂O₅ = 17 x 10⁻³ M/sec

Explanation:

Rate of reaction =

Where

dx = Change of concentration of reactants or products

dt = Change in time

According to chemical reaction

                       2 N₂O₅(g) → 4 NO₂(g)+O₂(g)

       Rate of disappearance of N₂O₅ = Rate of appearance of O₂
