Rate Determining Step -

The overall rate of reaction is controlled by the slowest step in a reaction called the rate determining step.

- wherein

e.g.

$2H_{2}O_{2}\xrightarrow[alkaline\ medium]{I^{-}}2H_{2}O+O_{2}$

$r=\frac{-d[H_{2}O_{2}]}{dt}=K[H_{2}O_{2}][I^{-}]$

$H_{2}O_{2}+I^{-}\underset{slow}{\rightarrow}H_{2}O+IO$

$H_{2}O_{2}+IO^{-}\underset{fast}{\rightarrow}H_{2}O+I+O_{2}^{-}$

As wehave learned in zero order reaction unit of rate constant it is zero order reaction then half life of the reaction will be

$t_{\frac{1}{2}}= \frac{c_{o}}{2k}=\frac{5\mu g}{2\times 0.05\mu g}/year=50years$
