Problem

In a first order reaction, the initial conc. of the reactant was M/10. After 8 minutes 20 seconds the conc. becomes M/100. What is the rate constant? (A) 5×10−35 \times 10^{-3} second −1^{-1} (B) 2.303×10−52.303 \times 10^{-5} second −1^{-1} (C) 2.303×10−42.303 \times 10^{-4} second −1^{-1} (D) 4.606×10−34.606 \times 10^{-3} second −1^{-1}
