Calculate the half-life for the hydrolysis reaction under these conditions.

More information is available on this project's attribution page.Then divide by the initial concentration, multiplying the fraction by 100 to obtain the percent completion.Solution: A We can calculate the half-life of the reaction using Equation 14.28: Thus a first-order chemical reaction is 97% complete after 5 half-lives and 100% complete after 10 half-lives.This is not true for zeroth- and second-order reactions.

The half-life of a first-order reaction is The Half-Life of a First-Order Reaction This plot shows the concentration of the reactant in a first-order reaction as a function of time and identifies a series of half-lives, intervals in which the reactant concentration decreases by a factor of 2.

Using ) and a characteristic value for each radioactive isotope.
