**Half-life equation Ask Me Help Desk**

Radioactive Half-Life Formula A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay. For example, if the half-life of a 50.0 gram sample is 3 years, then in 3 years only 25 grams would remain.... As you can might be able to tell from Graph 1,Half life is a particular case of exponential decay. One in which 'b' is $$ \frac 1 2 $$. So, generally speaking, half life â€¦

**Half-life equation Ask Me Help Desk**

The half-life of a chemical reaction is defined as the time required for half the amount of a reactant to be converted into product. To find the half-lives of different order reactions, we use integrated rate laws and rate constants to relate concentration to time. There are three different rate laws that can be used to find the half-life of a chemical reaction: zero, first, and second order....

You can use the decay equation N = N 0 e-Î»t to find the value of N for any value of t if you're given Î» and the number of undecayed nuclei you start off with, N 0. Worked example How to use the decay equation to calculate the number of nuclei remaining after a certain time.... By definition, the half life of any reaction is the amount of time it takes to consume half of the starting material. For a second-order reaction, the half-life is inversely related to the initial concentration of the reactant (A). For a second-order reaction each half-life is twice as long as the life span of â€¦

## How To Find Half Life Equation

### I do not have the decay constant but, by using the half-life information, I can find it. (Since this is a decay problem, I expect the constant to be negative. If I end up with a positive value, I'll know that I should go back and check my work.)

- Working out electron-half-equations and using them to build ionic equations. In the example above, we've got at the electron-half-equations by starting from the ionic equation and extracting the individual half-reactions from it.
