Explanation:
Half-life of tritium= 12.33 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the age of the sample:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = age of sample = 5 years
a = let initial amount of the reactant = 100 g
a - x = amount left after decay process = a g
Now put all the given values in above equation, we get
Thus 75.8 percentage of a sample will remain after 5 years have passed.
