Answer:
Half-life = 1.21x10⁻⁴ years⁻¹
Explanation:
The kinetics decay of ¹⁴C follows the first order reaction. That means half-life of ¹⁴C is defined as:
Half-life = ln 2 / K
<em>Where K is decay constant.</em>
<em />
As decay constant of ¹⁴C is 5730 years, half-life is:
Half-life = ln 2 / 5730 years
<em>Half-life = 1.21x10⁻⁴ years⁻¹</em>
