For the reaction A → B the following graph was obtained. The time required (in seconds) for the concentration of A to reduce to $\displaystyle 2.5 \mathrm{~g} \mathrm{~L}^{-1}$ (if the initial concentration of A was $\displaystyle 50 \mathrm{~g} \mathrm{~L}^{-1}$ ) is $\displaystyle \_\_\_\_$. (Nearest integer) Given : $\displaystyle \log 2=0.3010$
