Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
k is rate constant
Given that:- k = 0.27 (day)⁻¹
= 0.63 mg/L
mg/L
Applying in the above equation as:-



<u>Approximately 22.37 days, will it take for the water to be safe to drink.</u>
