Question
Dinitrogen pentoxide decomposes via a first order reaction.
Rate = K[N₂O5], k = 6.93 x 10°3 s-1
The concentration of N₂O5 is initially 0.500 mol/L. After 100 s it has dropped to 0.250 mol/L and after 200 s it has dropped to
0.125 mol/L. What is the concentration after 150 s?
HOW DO WE GET THERE?
Use the first order concentration-time equation to determine [N₂O5] remaining after 150 s.
[N₂05]t = 150
X mol/L
