Hello,
I have a question about a rate law problem. The problem is:
The reaction 2NO2 → 2NO + O2 follows the rate law
Δ[O2]/Δt=1.50*10-2[NO2]2
at 250. K.
If the initial concentration of NO2 is 1.00 M, how long will it take for [NO2] to reach 31.8% of its initial value?
I do not know what to do with the NO2 squared on the right because that makes it seem like an instantaneous concentration, and I need the average concentration over time. Could someone help?
Thanks!
