Step-by-Step Solution:
Step 1 of 3

Solution 25Q:

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 =
