Q. A graph plotted between log $t_{50 \%}$ vs. log concentration is a straight line. What conclusion can you draw from the given graph
NTA Abhyas
NTA Abhyas 2022
A
$n=1,t_{1 / 2}=\frac{0.693}{k}$
B
$n=2,t_{1 / 2}=\frac{1}{a}$
C
$n=1,t_{1 / 2}=\frac{1}{k . a}$
D
none of these
Solution:
$t_{1 / 2}\alpha a^{1 - n}$
or $t_{1 / 2}=ka^{1 - n}$
$logt_{1 / 2}=logk+\left(\right.1-n\left.\right)loga$
so slope $=1-n$
or $1-n=0$
or $n=1$
