Explain the concept of half-life.
Step 1 of 3
Half life is the time required for a quantity to fall to one-half of its initial value.
It is denoted by t1/2.
For example: Consider reaction has a half-life of 200 seconds, and the initial concentration of the reactant is 2.0 M, the concentration will fall to 1.0 M in 200 s.
The half life period is different for different type of reaction.
For first order reaction,
The half life t1/2 = where, k is the rate constant for the reaction.
Similarly , for second order reaction.
half life t1/2 =
