Answer:
28.43 min
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = min⁻¹
Initial concentration = 0.1 M
Final concentration = M
Time = ?
Applying in the above equation, we get that:-
