Answer:

The rate constant for a first order reaction is 60 s 1. How much time will It take to reduce the initial concentration of the reactant to its 1/6 th value? Answer: Question 9. For a first order reaction, show that time required for 99% completion is twice the time required for the completion of 90% of reaction…

Explanation:

The rate constant for a first-order reaction is equal to the negative of the slope of the plot of ln[H 2 O 2] ... (from 6.00 hours to 12.00 hours), it decreases from 0.500 M to 0.250 M; ... The half-life of a reaction is the time required to decrease the amount of a given reactant by one-half. The half-life of a zero-order reaction decreases as ...
