In chemical kinetics, the reaction half-life is the time needed for half of a reactant in a chemical reaction to be depleted. It is the same as the nuclear half-life involved in nuclear decay, which is a first-order reaction.
Famous quotes containing the words reaction and/or life:
“In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.”
—Hannah Arendt (1906–1975)
“I describe family values as responsibility towards others, increase of tolerance, compromise, support, flexibility. And essentially the things I call the silent song of life—the continuous process of mutual accommodation without which life is impossible.”
—Salvador Minuchin (20th century)
