The time for half life period of a certain reaction A→Products is...
The time for half-life period of a certain reaction A is the amount of time it takes for half of the reactant to be depleted. It is a characteristic property of the reaction and depends on the rate constant of the reaction.

The half-life period, denoted as t1/2, can be calculated using the following equation:

t1/2 = ln(2) / k

where ln(2) is the natural logarithm of 2 and k is the rate constant of the reaction.

The half-life period can vary depending on the specific reaction and its rate constant. Some reactions can have very short half-life periods, while others can have very long half-life periods.
