Chapter 6, Problem 6B.2ST

Interpretation Introduction

Interpretation:

The reaction in which a DNA double helix re-forms has to be classified.

Concept Introduction:

Order of a reaction:  The sum of exponents of the concentrations in the rate law for the reaction is said to be order of a reaction.

$\text{Order}\text{= }\text{x+y}$

Half-life is the time required for one half of a reactant to react.

For first order reaction $-kt=\ln \left(\frac{\left[A\right]}{\left[A_0\right]}\right)$

$\left[A\right]$ is the concentration of reactant A at time t ${\left[A\right]}_0$ is the  initial concentration of reactant, k is the rate constant.

Intergrated rate eqaution for a second order reaction is,

$\frac{1}{\left[A\right]}=\frac{1}{{\left[A\right]}_0}+kt$

$\left[A\right]$ is the concentration of reactant A at time t ${\left[A\right]}_0$ is the  initial concentration of reactant, k is the rate constant.
