Data for the decomposition of $\mathrm{SO}_{2} \mathrm{Cl}_{2}$ according to the equation $\mathrm{SO}_{2} \mathrm{Cl}_{2}(g) \longrightarrow \mathrm{SO}_{2}(g)+\mathrm{Cl}_{2}(g),$ were given in Problem 13.53. Show graphically that these data fit a first-order rate law. Graphically determine the rate constant for the reaction.

Key Concepts

Rate Constant Determination

The rate constant, k, quantifies the rate at which a reaction occurs. In a first-order reaction, k can be directly obtained from the slope of the ln[A] versus time graph; specifically, the slope is equal to -k. This experimental determination of k is a critical step in characterizing the kinetic behavior of a reaction.

First-order Reaction Kinetics

A first-order reaction is one where the rate is directly proportional to the concentration of a single reactant. The rate law for such reactions is expressed as d[A]/dt = -k[A], and upon integration, it yields the linear relationship ln[A] = ln[A]? - kt. This relationship is fundamental in kinetics as it simplifies the analysis of reaction behavior over time.

Graphical Analysis of Kinetics

Graphical methods are widely used in kinetics to determine the order of a reaction. For a first-order reaction, plotting the natural logarithm of the reactant's concentration (ln[A]) versus time should produce a straight line. The linearity of this graph is a strong indication that the reaction follows a first-order rate law, and the slope of the line provides valuable kinetic information.
