નીચેનામાથી અર્ધઆયુનું કયું સમીકરણ સાચું છે?
A
$ {(t)_{1/2}} = \log \,2 $
B
$ {(t)_{1/2}} = \frac{\lambda }{{\log 2}} $
C
$ {(t)_{1/2}} = \frac{\lambda }{{\log \,{\rm{2}}}}(2.303) $
D
$ {(t)_{1/2}} = \frac{{2.303\,{\rm{ log\, 2\,}}}}{\lambda } $
Solution
(d) ${T_{1/2}} = \frac{{{{\log }_e}\,2\,}}{\lambda } = \frac{{2.303\,{{\log }_{10}}\,2\,}}{\lambda }$
