WebAnswer: d) zero. Q-8: Match the graphical study with the order of the reactions: Answer: I-C, II-A, III-B. Explanation: Because the rate of a zero order reaction is independent of time, Graph 1 depicts a zero order reaction. The half life of a first order reaction is 0.693/k. It clearly demonstrates that it is unaffected by the initial ... WebApr 5, 2024 · The key concept of zero order reaction is that, in a zero order reaction, the rate of the reaction will never depend on the concentration of the reacting species. Half-life is the concept of time, so …
WebFeb 12, 2024 · Since this is a zero-order reaction, the half-life is dependent on the concentration. In this instance, the half-life is decreased when the original concentration is reduced to 1.0 M. The new half-life is 80 seconds. Reaction B represents a zero-order … This indicates that the half-life of a first-order reaction is a constant. Figure … WebThe half-life of a reaction describes the time needed for half of the reactant(s) to be depleted, which is the same as the half-life involved in nuclear decay, a first-order reaction. For a zero-order reaction, the half-life is given by:
WebThe half-life of a zero-order reaction increases as the initial concentration increases.
