Chapter 13, Problem 90RQ

${\text{SO}}_{\text{2}}{\text{Cl}}_{\text{2}}$ decomposes in a first-order process with a half life of $\text{4}\text{.88 }\times {\text{ 10}}^{\text{3}}\text{s}$. If the original concentration of ${\text{SO}}_{\text{2}}{\text{Cl}}_{\text{2}}$ is 0.012 M, how many seconds will it take for the ${\text{SO}}_{\text{2}}{\text{Cl}}_{\text{2}}$ to reach 0.0020 M?
