Answer:
The answer to your question is in the attachment.
Explanation:
Tell me if you understand
Answer:
t = 49.20 years
Explanation:
Half life expression for first order kinetic is:
Half life = 12.3 years
Where, k is rate constant
So,
The rate constant, k = 0.05635 years⁻¹
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
is 6.25 % of
. So,
= 0.0625
t = ?
<u>t = 49.20 years</u>
