Radioactive Decay

Postby Amy Lefley 1J » Tue Mar 05, 2019 2:45 pm

How do we know that radioactive decay is a first order reaction?

because the rate of decay is directly proportional to the concentration of atoms

Because it has a constant half-life. All first-order reactions have constant half-lives.

It was through experimental verification that we were able to tell over a given period of time, now called a radioactive substance's half life, that half of the substance would decay away; this fits within our model of a first order process.
