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). WebThe formula for the half-life is obtained by dividing 0.693 by the constant λ. Here λ is called the disintegration or decay constant. Hence the formula to calculate the half-life of a substance is: t1 2 = 0.693 λ t 1 2 = 0.693 λ Where, t1 2 t …
