Question

For nth order reaction, the half-life period, $t_{1/2}$ is proportional to initial concentration as

• A. ${\frac{1}{a}}^{n-1}$
• B. $a^{n+1}$
• C. $a^{n-1}$
• D. ${\frac{1}{a}}^n$

Answer 1

Answer: (A)

$t_{1/2}\propto {\frac{1}{a}}^{n-1}$
where, $t_{1/2}=$ half-life period
$a=$ initial concentration
$n=$ order of the reaction
