In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant).

Plugging in the half-life given in the problem: k = 0.693/1620 years = 4.28 x 10-4/year. Radioactive decay is a first order rate reaction, so the expression for the rate is: log 10 X 0 /X = kt/2.30. اشتها اور قوی بدون عوارض
