Graph half life
Webhalf-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half. The … WebSo now we can solve for the half-life. Just divide both sides by k. So we get the half-life is equal to one over k times the initial concentration of A. And so here's our equation for the half-life for a second order reaction. Notice this is very different for the half-life for a …
