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 $t_{\frac{1}{2}} \propto a^{1-n}$
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.
