Question

The half life time of 2g sample of radioactive nuclide x is 15 min the half life of 1g sample of x is

Answer 1

Radioactive disintegration follows a first order Kinetics.

A half - life period of a first order reaction is independent of the initial concentration of the substance.

From the facts above ,we realize that the half life is the same .

hence the half life of 1 gram of the substance is 15 minutes

Answer 2

Answer:

15 min

Explanation:

T 1/2=ln(2)/lmda
