What is meant by half-life period?
Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.
What is a half-life period of a reaction?
The half-life of a reaction is the time required for a reactant to reach one-half its initial concentration or pressure. For a first-order reaction, the half-life is independent of concentration and constant over time.
How do you find the half-life period in chemistry?
The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value. The half-life of a first-order reaction does not depend upon the concentration of the reactant. It is a constant and related to the rate constant for the reaction: t1/2 = 0.693/k.
What is half-life period shaala?
Half life of a reaction is defined as the time required for the reactant concentration to reach one half of its initial value. Concept: Half Life Period of a Reaction.
