Problem: The decomposition of sulfuryl chloride (SO2Cl2) is a first-order process. The rate constant for the decomposition at 660 K is 4.5 x 10–2 s–1. At what time will the partial pressure of SO2Cl2 decline to one-tenth its initial value?

FREE Expert Solution

The integrated rate law for a first-order reaction is as follows:


ln[A]t = -kt + ln[A]o


where: 

[A]t = concentration at time t

k = rate constant

t = time

[A]0 = initial concentration
