Half life calculator

Introduction to Half Life Calculator:

In the branch of nuclear chemistry, the half life equation calculator plays an important role in determining the decay of radioactive isotopes. Our half life problem solver is a powerful tool for knowing the half life of an element.

Whether it's a first order half life decay or a second order half life decay our half life formula calculator will find it for you explaining each step for free.

What is meant by half-life?

Half-life or half-life period is the time required to convert 50% of the reactant into products or decomposition of 50% of isotopes. An element or compound can take some seconds, minutes or years to decompose. For example, the half-life period of N2O5 at 45 C is 24 minutes meaning that it will take only 24 minutes for N2O5 to decompose 50% at 45 C.

Relevant: The stoichiometry of the reaction can be determined by our calculator for stoichiometry.

The formula of half-life used by half life problem solver:

The formula used to calculate half life varies from the order of the reaction which means it may be different for one reaction or different for another. The formula for finding first-order, second order, and third-order half-life reactions used by our half life calculator is:

[t1/2] = ln(2)/ƛ

The other formulas for finding the half life of radioactive elements are:

[t1/2]1 = 0.693/k

[t1/2]2 = 1/ka

[t1/2]3 = 1.5/ka2

Where, for the 1st, 2nd, and 3rd order reaction the [t1/2]1,[t1/2]2, and [t1/2] 3 are the half life periods respectively and the “a” is used as an initial concentration or initial amount of the substance or the reaction.

Why is finding the half-life important?

Half-life is a time when half of the atoms in the radioactive material or a substance decay. Finding the half-life is important as it tells how the radioactive substances behave in different time zones. It helps us to predict the behavior a certain element has in the past. This information is important in various fields i.e., in medicine, nuclear energy environmental sciences, etc. It helps us in various ways,

• Knowing the time to store nuclear waste
• Knowing about the unknown isotopes
• Making safe medical treatments

It is also used to find the age of the organic compounds. For example, to identify the age of an organic compound scientists generally use Carbon-14 which helps them to calculate the exact age of an organic compound.

Calculation of time Elapsed using half life calculator with steps:

Half life calculations are tricky and take time but our half life decay calculator is here to help. But here we will give you some examples so you better understand how to calculate half-life manually,

Example 1:

If the initial concentration of HI is 0.05M and the rate constant is 0.079 dm^3 mol^-1s^-1 at 508 C having an expression of Rate = k[HI]2, then find the half-life period of the following reactions,

2HI ⇆ H2 + I2

Solution:

The rate constant shows that the reaction is second order so we will implement the 2nd order formula on the given reaction.

[t1/2]2 = 1/ ( 0.079 dm^3 mol^-1s^-1 * 0.050 mol dm^-3

[t1/2]2 = 253 seconds

Therefore, in 253 seconds half of HI which is 0.05/2 = 0.025 moles are decomposed.

Example 2:

If the decay constant of a substance is 0.96 s^-1. Then find the half life of the substance.

Solution:

We will implement the first-order reaction formula in it,

[t1/2]1 = 0.693/0.96

[t1/2]1 = 0.7seconds

So, it will take 0.7 seconds for the above substance to decay.
