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). greenfield winter carnival
