For a first-order reaction, the half-life is constant. It depends only on the rate constant k k and not on the reactant concentration. It is expressed as t1/2=0.693k t 1 / 2 = 0.693 k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0. A certain first-order reaction (A→products A → p r o d u c t s ) has a rate constant of 9.30×10−3...
Half-life equation for first-order reactions: t1/2=0.693k where t1/2 is the half-life in seconds (s), and k is the rate constant in inverse seconds (s−1). a) What is the half-life of a first-order reaction with a rate constant of 4.80×10−4 s−1? b) What is the rate constant of a first-order reaction that takes 188 seconds for the reactant concentration to drop to half of its initial value?

please help explain this to me step by step, thank you so much! A reactant decomposes with a half-life of 15.7 s when its initial concentration is 0.491 M. When the initial concentration is 2.67 M, this same reactant decomposes with a half-life of 85.5 s. What is the order of the reaction? What is the value and unit of the rate constant for this reaction? Unit: 0 M-s-1 k=11 4.4 ×10
The half-life of a reaction, t1/2, is the time it takes for the reactant concentration [A] to decrease by half. For example, after one half-life the concentration falls from the initial concentration [A]0 to [A]0/2, after a second half-life to [A]0/4, after a third half-life to [A]0/8, and so on. on. For a first-order reaction, the half-life is constant. It depends only on the rate constant k and not on the reactant concentration. It is expressed as t1/2=0.693k For a...
