Question:medium
If the rate constant of a reaction is 0.03 s$^{-1}$, how much time does it take for a 7.2 mol L$^{-1}$ concentration of the reactant to get reduced to 0.9 mol L$^{-1}$?
(Given: log 2 = 0.301)

(Given: log 2 = 0.301)
Show Hint
For a first-order reaction, the relationship between concentration and time is logarithmic. Always ensure to use the integrated rate law for calculations involving concentration changes over time.
