Half life for zero order reaction
WebFeb 12, 2024 · Notice that, for first-order reactions, the half-life is independent of the initial concentration of reactant, which is a unique aspect to first-order reactions. The practical implication of this is that it takes as much time for [A] to decrease from 1 M to 0.5 M as it takes for [A] to decrease from 0.1 M to 0.05 M. WebFeb 12, 2024 · In First order reactions, the graph represents the half-life is different from zero order reaction in a way that the slope continually …
