How long will tritium last?
The half-life of tritium is about 12.3 years, meaning it takes that much time for half of the tritium to decay. However, tritium can persist in the environment for a longer time due to its constant formation in the upper atmosphere and mixing in with water sources.
How much sample of 10g of tritium with half life of 12.32 after 2 half lives?
After 2 half-lives (two half-lives of tritium is 12.32 x 2 = 24.64 years), the initial 10g sample of tritium would have decayed by half to 5g.
What is the fraction of a sample of tritium that remains undecayed after fifty years?
After 50 years, approximately 50% of tritium will remain undecayed in a sample. Tritium has a half-life of about 12.3 years, which means that the amount of undecayed tritium decreases by half every 12.3 years.
Arrange in the order of half life s35 p32 H3 C14?
The order of half-life from shortest to longest is: P32 (phosphorus-32), S35 (sulfur-35), C14 (carbon-14), and H3 (tritium).
What is first order kinetics?
First-order kinetics refers to a reaction in which the rate is directly proportional to the concentration of one reactant. This means that the reaction proceeds at a speed determined by the concentration of the reactant involved, leading to a constant half-life. The rate constant for a first-order reaction has units of 1/time.

What is the half life tritium?
The half-life of tritium is 12.32 years (12 years 3 months and 26-ish days).

A first order reaction is found to have a rate constant t k equals .0000739 find the half life of this reaction?
Since the reaction is first-order, the half-life is constant and equals ln(2)/k, and the units of k are s-1. In this case, the half-life is ln(2)/(.0000739 s-1) = 9379.529 seconds.
What has the author C R Ruby written?

What is the half life of the Radioisotope H3?
The half-life of the radioisotope tritium (H-3) is about 12.32 years. This means that it takes approximately 12.32 years for half of a sample of tritium to decay into helium-3.
What is the rate constant when a first-order reaction is 35.5 percent complete in 4.90 minutes at 25 degrees celsius?
To calculate the rate constant for a first-order reaction, you can use the natural logarithm function. Rearrange the integrated rate law for a first-order reaction to solve for the rate constant. In this case, k = ln(2)/(t(1/2)), where t(1/2) is the half-life of the reaction. Given that the reaction is 35.5% complete in 4.90 minutes, you can use this information to find the half-life and subsequently calculate the rate constant.
What is the order of reaction if the half life of a reaction is halved as the initial concentration of the reactant is doubled.?
Second order. If the half life of a reaction is halved as the initial concentration of the reactant is doubled, it means that half life is inversely proportional to initial concentration for this reaction. The only half life equation that fits this is the one for a second-order reaction. t(1/2) = 1/[Ao]k As you can see since k remains constant, if you double [Ao], you will cause t(1/2) to be halved.
Why half life of first order reaction does not depend upon the concentration?
half life of a chemical reaction is the time which is required and it does not depend upon concentration of reactantuired to convert hlaf of reactant into product and it depend upon the nature of reaction and condition of r
