At $\displaystyle 30^{\circ} \mathrm{C}$, the half life for the decomposition of $\displaystyle \mathrm{AB}_2$ is $\displaystyle 200$ s and is independent of the initial concentration of $\displaystyle \mathrm{AB}_2$. The time required for $\displaystyle 80 \%$ of the $\displaystyle \mathrm{AB}_2$ to decompose is Given: $\displaystyle \log 2=0.30$ $\displaystyle \log 3=0.48$
