then.. .. integrated fee equations

.. (1).. zero order... ... ... ..[A] = -kt + [Ao]

.. (2).. first order... .... .. ln[A] = -kt + ln[Ao]

.. (2).. 2d order.. .. 1/[A] = +kt + 1/[Ao]

and for those who notice.. [Ao] is the beginning concentration.. we pick one price and start the reaction.. so [Ao] is a constant

and "k" is a constant... that is our fee constant

and [A] varies as "t" varies.. the concentration changes over time

so that ALL of those equations are a line of the shape y = mx + b if we define y and x correctly
