Which is the correct expression for half-life
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)${T_{1/2}} = \frac{{{{\log }_e}\,2}}{\lambda } = \frac{{2.303\,{{\log }_{10}}\,2\,}}{\lambda }$
