The disintegration of a radioisotope, such as I-131 to Xe-131, is another example of a first-order reaction.

It has a half-life of 8.0 days.

I-131 -> Xe-131 + e

If you start with 1.40 g I-131, how many grams of I-131 will be left after the following days?

08 days: g,

16 days: g,

20 days: g,

24 days: g,

30 days: g

32 days: g

47 days: g
