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:
“Sole and self-commanded works,
Fears not undermining days,
Grows by decays,
And, by the famous might that lurks
In reaction and recoil,
Makes flames to freeze, and ice to boil.”
—Ralph Waldo Emerson (1803–1882)
“To suppose such a thing possible as a society, in which men, who are able and willing to work, cannot support their families, and ought, with a great part of the women, to be compelled to lead a life of celibacy, for fear of having children to be starved; to suppose such a thing possible is monstrous.”
—William Cobbett (1762–1835)
