It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t1/2 = [R]0/2k. For a first-order reaction, the half-life is given by: t1/2 = 0.693/k. city discovered in 1718WebMar 8, 2024 · The zero order integrated rate law is [A] = -kt + [A]initial. Therefore, a zero order reaction is usually graphed as [A] vs. time, which should be a straight line. If it isn't a straight line then it is not a zero order reaction.
