What is a half-life ?
A) It is a special case when the rate constant equals one-half. (i.e., k = 0.5)
B) A period of time required for the concentration of a reactant to reduce to one-half its original value.
C) It is a rate law that is one-half order: (i.e., Rate = k [A]1/2)
D) A period representing one-half the amount of time required for an initial concentration of a reactant to reduce to 0.00 M.
E) A period representing the amount of time required for an initial concentration of a reactant to reduce to 0.5 M.
