Q. For which of the following represents the expression for three/forth life of reaction?
Chemical Kinetics
A
$\frac{k}{2.303} \log 4 / 3$
B
$\frac{2.303}{k} \log 3 / 4$
C
$\frac{2.303}{k} \log 4$
D
$\frac{2.303}{k} \log 3$
Solution:
$t_{3 / 4}=\frac{2.303}{k} \log \frac{1}{\left(1-\frac{3}{4}\right)}=\frac{2.303}{k} \log 4$
