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 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 t 1/2 = 1 k[A ] 0 Part A A certain first-order reaction ( A→products ) has a rate constant of 9.90×10−3 s −1 at 45 ∘...

Part A The rate constant for a certain reaction is k = 6.30×10−3 s−1 . If the initial reactant concentration was 0.150 M, what will the concentration be after 9.00 minutes? Express your answer with the appropriate units. Part B A zero-order reaction has a constant rate of 4.90×10−4 M/s. If after 60.0 seconds the concentration has dropped to 2.50×10−2 M, what was the initial concentration? Express your answer with the appropriate units.

Part A: The rate constant for a certain reaction is k = 2.30×10−3 s−1 . If the initial reactant concentration was 0.450 M, what will the concentration be after 3.00 minutes? Part B: A zero-order reaction has a constant rate of 4.10×10−4 M/s. If after 35.0 seconds the concentration has dropped to 5.50×10−2 M, what was the initial concentration? Express your answer with the appropriate units.

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...
