Question

For which of the following is the half-life dependent on the concentration of the reactant? *a zero-order reactionb first-order reactionc second-order reaction

Answer 1

For a zero-order reaction, we will have that the half-life will depend only on the rate constant, that is, it does not depend on the concentration.

The same happens with reactions of first-order they are independent of the initial concentration.

On the contrary, for the reaction of second-order, the concentration will influence the half-life of the compound. Therefore we will have half-life depends on reactant concentration for:

Answer: c. Second-order reaction
