t_100 % is the time required for the 100 % completion of the reaction while t_1 / 2 is the time required for 50 % of the reaction to be completed.…
$\displaystyle \mathrm{t}_{100 \%}$ is the time required for the $\displaystyle 100 \%$ completion of the reaction while $\displaystyle \mathrm{t}_{1 / 2}$ is the time required for $\displaystyle 50 \%$ of the reaction to be completed. Which of the following option correctly represents the relation between $\displaystyle \mathrm{t}_{100 \%}$ and $\displaystyle \mathrm{t}_{1 / 2}$ for zero and first order reactions respectively ?
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle t_{100 \%}=2 t_{1 / 2} \text { and } t_{100 \%}=\left(t_{1 / 2}\right)^{\infty}$
