In a zero order reaction 20%
WebDec 19, 2015 · Simply put, the time needed for 50% of a reaction to be completed will represent that reaction's half-life. In your case, you know that your first-order reaction is … 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).
