Chapter 11.3, Problem 11.6PSP

Interpretation Introduction

Interpretation:

The time required for the concentration of insecticide to drop to one by tenth of its initial value has to be calculated.

Concept Introduction:

The integrated rate equation for first order reaction is given below.

  $kt=\ln \frac{{\left[A\right]}_o}{{\left[A\right]}_t}$

Where,

    $\begin{array}{l}k=\text{}rate\text{}cons\tan t\\ \\ t=timetakentochangetheconcentrationfrom{\left[A\right]}_{o}to{\left[A\right]}_t\\ \\ {\left[A\right]}_o=initialconcentrationofA\\ \\ {\left[A\right]}_t=finalconcentrationofA\end{array}$
