For a second order reaction, the half-life is equal to:_____.

Chemistry
1 answer:
gtnhenbr [62]3 years ago

Answer:

Half life = 1 / k[Ao]

Explanation:

From:

1/ [A] = kt + 1/ [Ao]

Isolating t on its own, we have:

kt = 1 / [A] - 1 / [Ao]

t = 1 / [Ao] / k

Re-arranging we have:

t = 1 / k [Ao]

The t represents the t=half life of the second order reaction and the formula can be re-written as:

t1/2 = 1 / k [Ao]

This is so because second order reaction decreases at a much faster rate than zero and first order reactions and there slopes decreases to zero at a much faster rate.

7.) Carbon-14 is a radioactive isotope of carbon. The half-life of carbon-14 is approximately 5,730 years. The short half-life of carbon-14 means it cannot be used to date fossils that are allegedly extremely old, e.g. dinosaurs the evolution alleges lived millions of years ago. Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).

You should clean up after every investigation because if you leave a mess, maybe another detective will come in and get lost because of the mess you left.
