Web8 years ago. 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). WebHalf life formula. By using the following decay formula, the number of unstable nuclei in a radioactive element left after t can be calculated: N (t) = N_0 \times 0.5^ { (t/T)} N (t) = N 0 × 0.5(t/T) In this equation: N (t) refers to the quantity of a radioactive element that exists after time t has elapsed. N (0) refers to the initial amount ...
