how to calculate mole concenration?

60x60x24 = 1day

36*10^2 * 24 = 8640 *10 ^2

86.40 * 10^4 * 60 = 51.8 * 10^6??

    The units of "k" are not dimensionally homogeneous with this problem.  Should be mole / (L * sec).  The  value of the rate constant 60 mol/sec is extraordinarily high for this problem.  did you forget a negative sign?

    given the units of M/s, the rxn is zero order.. therefore the integrated rate equation is.

    .. [At] = -kt + [Ao]

    where

    .. t = 20 mon * (1yr / 12mon) * (365.25day /.yr) * (3600s / day) = 5.26x10^7 sec

    you get to finish
