Question

The term half-life, as applied to a reactant in a chemical reaction means: the time required for half of the maximum amount of product to be formed. the time taken for the concentration of a reactant to decrease by a factor of 1/2. half of the time it ta kes for all of a reactant to be consumed. the value of time which gives a value of 1/2 when substituted into the expression kt.

Answer 1

The term half lime means: the time taken for the concentration of a reactant to decrease by a factor of 1/2.

Step-by-step explanation:

In kinetics, the term half-life refers to the time that it takes to decrease the concentration of a reactant to half its initial concentration. Half-life depends on the reaction order, on the rate constant and, except for first-order kinetics, on the initial concentration of the reactant.
