Half life period of a radio active eleme...

Half life period of a radio active element is 1500 years. Find the value of disintegration constant interms of second.

Text Solution

Verified by Experts

`lambda=(0.693)/(t^(1//2)) =(0.693)/(1500 yrs)`
`=(0.693)/(1500xx365xx24xx60xx60 sec)`
`=0.1465 xx10^(-10) sec^(-1)`
