MCQ
For the first order reaction with rate constant $k$, which expression gives the half-life period ? (Initial concentration $ = a$)
- A$\frac{{{1^2}}}{k}$
- B$\frac{1}{{ka}}$
- ✓$\frac{{0.693}}{k}$
- D$\frac{3}{{2k{a^2}}}$
✓
Answer
Correct option: C.
$\frac{{0.693}}{k}$
c
(c)${t_{1/2}} = \frac{{0.693}}{k}$
(c)${t_{1/2}} = \frac{{0.693}}{k}$
