Find the initial concentration of NO2 if the concentration after 2.00 min is 0.113. k = 0.331 1/(M * s)
2 NO2 (g) + N2 (g) --> 2 N2O (g) + O2 (g)
This is a second order reaction.
(1/A) - (1/Ao) = akt
Plug in 0.113 for A, 0.331 for k, 2 for a,and 2 for t then solv for Ao.
True, however, I keep getting a negative value which is not possible.
What is the unit for 0.113? Check the numbers in the post to make sure all are ok.
its concentration, so it should be mol/L
