At \(30^{\circ} \mathrm{C}\), the half life for the decomposition of \(\mathrm{AB}_{2}\) is \(200 \mathrm{~s}\) and is independent of the initial concentration of \(\mathrm{AB}_{2}\). The time required for \(80 \%\) of the \(\mathrm{AB}_{2}\) to decompose is

Given: \(\log 2=0.30\) \(\quad \log 3=0.48\)
