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)

  • Chemistry - ,

    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.

  • Chemistry - ,

    True, however, I keep getting a negative value which is not possible.

  • Chemistry - ,

    What is the unit for 0.113? Check the numbers in the post to make sure all are ok.

  • Chemistry - ,

    its concentration, so it should be mol/L
