Question

Example 4.40
The half life period of a substance is 50 minutes at a certain initial concentration. When the concentration is reduced
to one half of the initial value, the half-life period is 25 minutes. Calculate the order of the reaction.​

Answer 1

Answer:

It is given that the half life of the compound is reduced to half (50 mins. to 25 mins.) when initial concentration is reduced to half. This means that half life is directly proportional to initial concentration. So, the order of the reaction is zero.
