Consider the first-order half-life decay of ${}_{6}^{14}C$. Given that the half-life is 5730 yrs,

calculate the rate constant for this process in ${s}^{-1}$ (use the conversion 365.24 days = 1 yr).

Given an initial concentration of 0.50M, calculate the initial rate of this process in M/s.

Equations you will need:

${t}_{1/2}=\frac{\mathrm{ln}2}{k}$

(first-order half-life)

$r(t)=k{[}_{6}^{14}C]$

(first-order rate law)

Answers:

$k=3.83\times {10}^{-12}{s}^{-1}$

$r(t)=1.92\times {10}^{-12}M/s$
