![[A_t]=[A_0]e^{-kt}](/tpl/images/0539/1305/1ef89.png)
![[A_t]](/tpl/images/0539/1305/5262c.png)
is the concentration at time t
![[A_0]](/tpl/images/0539/1305/9a686.png)
is the initial concentration
![\frac {[A_t]}{[A_0]}](/tpl/images/0539/1305/0d33c.png)
= 0.0625![\frac {[A_t]}{[A_0]}=e^{-k\times t}](/tpl/images/0539/1305/16cf4.png)
