Based on the experiment scenario:
1. state your hypothesis.
2. how would you set up a
controlled experiment? describe
your experimental setup.
3. what is the control group?
4. what is the experimental
group(s) in this experiment?
5. what variables must be kept
constant in this experiment?

The age of a bone or other sample of organic matter by its carbon-14 content is 16252 years

Explanation:

Expression for rate law for first order kinetics is given by:

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process  

a) for completion of half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

b) for completion of 14 % of reaction

The age of a bone or other sample of organic matter by its carbon-14 content is 16252 years
