Question

A decomposition reaction, with a rate that is observed to slow down as the reaction proceeds is found to have a half-life that does not depend on the initial concentration of the reactant. which of the following is most likely true about this reaction.


1. A plot of the natural log of the concentration of the reactant as a function of time will be linear.


2.) The half life of the reaction increases as the initial concentration increases.


3. a doubling of the initial concentration of the reactants results in a quadrupling of the rate. PLEASE EXPLAIN ANSWER!

Explanation / Answer

(1) above tells you that the reaction is not 0th order (where rate is constant)

(2) above tells you that it is not 1st order (where t1/2 doesn
