Half-life period of a radioactive element is 100 seconds. Calculate the disintegration constant and average life period. How much time will it take for 90% decay? |

Answer» Solution :`t^(1//2)=100 SEC` average LIFE period `tau=(1)/(lambda)=(1)/(0.00693)=1.44 sec^(-1)` `=(2.303)/(0.00693) LOG (100)/(10)` `=(2.303)/(0.00693) log 10=332.3 sec` |
