trapecia [35]

Answer:

option A

Step-by-step explanation:

given,

sample of tritium, ³H

$t_{1/2} = 12.32 years$

contents present of ³H = 5.25 mol

content of ³He = 6.35 mol

reaction

$^3H\rightarrow \ ^3He$

A₀ is the initial concentration

At is the concentration after time t

A₀ = 5.25 + 6.35 = 11.6 mol

At = 5.25

now,

$k = \dfrac{0.693}{t_{1/2}}$

$k = \dfrac{0.693}{12.32}$

k = 0.0563 /year

$ln(\dfrac{A_o}{A_t}) = k t$

$t = \dfrac{1}{k} ln(\dfrac{A_o}{A_t})$

$t = \dfrac{1}{0.0563} ln(\dfrac{11.6}{5.25})$

t = 14.1 yr

hence, the correct answer is option A
