1.	In a first order reaction, the concentration of the reactant decreases from 800 mol dm−3 to 50 mol dm−3 in 2×104s. The rate constant of the reaction in (s−1) is(IIT-JEE, 2003)
Answer» In a first order reaction, the concentration of the reactant decreases from 800 mol $d m^{- 3}$ to 50 mol $d m^{- 3}$ in $2 \times 10^{4} s .$ The rate constant of the reaction in $(s^{- 1})$ is (IIT-JEE, 2003)
