the time of a reaction
the extent of reaction
the initial conc. of the reactant
The half life of a radioactive element is 40 days. Calculate the average life
5.76 days
57.6 days
646 days
4.56 days
B.
57.6 days
We know,
Average life (T) = 1.44 x half life (t1/2)
Hence T = 1.44 x 40 or T = 57.6 days
So, average life of that radioactive element is 57.6 days.
