T1/2 depends inversely on k why ?
T1/2 depends inversely on k and directly on the initial concentration of the reactants in question. What is the order?
-is the order 0 or 2nd? I think it is 0 because the  is on top opposed to 1/
Radiochemical calculations of the form
ln(No/N) = kt where
k = 0.693/t1/2
are first order.
