Chapter 19, Problem 19.28QP

Interpretation Introduction

Interpretation:

Half-life has to be defined and the equation relating the half-life of a second-order reaction to the rate constant has to be derived.

Concept introduction:

Half-life: The time required for half of a reactant to be consumed in a reaction is said to be half-life.

• Half-life of a reaction is represented by the symbol as $t_{\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.}$
• Half-life is discovered by Ernest Rutherford's in 1907 from the original term half-life period.
• The half-life period is then shortened as half-life in early 1950s.
