MCQ
For which order reaction a straight line is obtained along with $x\,-$ axis by plotting a graph between half life $({t_{1/2}})$ and initial concentration $ 'a'$
  • A
    $2$
  • $1$
  • C
    $3$
  • D
    $0$

Answer

Correct option: B.
$1$
b
We know that $t_{\frac{1}{2}} \propto a^{1-n}$

The graph to be straight line $t_{\frac{1}{2}}$ should be independent of $a$ That is $1-n=0,$ hence $n=1$

It is a first order reaction.
