The First-Order Integrated Rate Law

[Mr.Thesaxman]

Consider the equation for the decomposition of SO2Cl2.

SO2Cl2 (g) → SO2 (g) + Cl2 (g)

The concentration of SO2Cl2 is monitored at a fixed temperature as a function of time during the decomposition reaction, and the following data are tabulated:

(a) Show that the reaction is first order and determine the rate constant for the reaction.

(b) Use the graph and the best fitting line in the previous example to predict the concentration of SO2Cl2 at 1900 s.
