Chapter 7, Problem 7.26E

Interpretation Introduction

Interpretation:

The activation energy for souring of milk has to be determined.

Concept Introduction:

The Arrhenius equation is the relationship between the temperature and rate constants and also involves the activation energy.  The mathematical form of Arrhenius equation involving the two rate constants $k_{\text{r1}}$ and $k_{\text{r2}}$ at temperature $T_1$ and $T_2$ respectively is shown below.

    $\ln \frac{k_{\text{r2}}}{k_{\text{r1}}}=\frac{E_{\text{a}}}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)$
