Nitrogen pentoxide decomposes according to equation :
2N₂O₅(g) --> 4NO₂(g) + O₂(g)
The first order reaction was allowed to proceed at 40°C and the data below were collected :
[N₂O₅] (M) Time(min)
0.400 0.00
0.289 20.0
0.209 40.0
0.151 60.0
0.109 80.0
what will be the concentration of n₂o₅ after 100 minutes?
