Answer:
1 day
Explanation:
Let the safe level = x
The current level = x + 0.2x = 1.2 x
Thus,
Half life = 3.8 days
Where, k is rate constant
So,
The rate constant, k = 0.1824 days⁻¹
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
So,
= x / 1.2 x = 0.8333
t = ?
t ≅ 1 day
