Answer:
It will take 3.3 s for [NOCl] to decrease to 0.042 M.
Explanation:
Integrated rate law for this second order reaction-
where, [NOCl] is concentration of NOCl after "t" time, is initial concentration of NOCl and k is rate constant.
Here, = 0.076 M, k = 3.2
and [NOCl] = 0.042 M
So,
or, t = 3.3 s
So, it will take 3.3 s for [NOCl] to decrease to 0.042 M.
Answer:
The mass left after 24.6 years is 25.0563 grams
Explanation:
The given parameters are;
The mass of the hydrogen-3 = 100 grams
The half life of hydrogen-3 which is also known as = 12.32 years
The formula for calculating half-life is given as follows;
Where;
N(t) = The mass left after t years
N₀ = The initial mass of the hydrogen-3 = 100 g
t = Time duration of the decay = 24.6 years
= Half-life = 12.32 years
The mass left after 24.6 years = 25.0563 grams.
