Question
Decay constant of a radioactive substance is 69.3sec-1, find t1/16 of the same substance.
Options
A.4 × 10-2 sec
B.2 × 10-2 sec
C.1 × 10-2 sec
D.none of these.
Solution
Given k = 69.3sec-1
Intial concentration = a0 Final concetration, a0 = a /16
Using t =
× 4
= 4 × 10-2sec.
Intial concentration = a0 Final concetration, a0 = a /16
Using t =
× 4= 4 × 10-2sec.
