Define half-life period.

Define Half-life of radioactive material. Derive an expression for half-life period

Give the graphical representation of half-life period reaction against concentration for first order reaction

The time for half-life period of a certain reaction, A rarr products is 1 h when the initial concentration of the reactant 'A' is 2.0 "mol" L^(-1) . How much time does it take for its concentration to come from 0.50 to 0.25 "mol" L^(-1) , if it is zero order reaction ?

The half-life period of any first order reaction:

If the half-life period of a zero order reaction with initial concentration 0.1 M is 32.4 min. What will be the half-life when the concentration is 0.5 M?

The half-life period of a first order reaction is 10 minutes. Starting with initial concentration 12 M, the rate after 20 minutes is

The relationship between rate constant and half life period of zero order reaction is given by _______.

The half life period of a radioactive element is 140 days. After 560 days, one gram of the element will reduced to :

The half life period of a first order chemical reaction is 6.93 minutes. The time required for the completion of 99% of the reaction will be (log2=0.301)

Answer the following questions: Define time period.
