Two substances A $(t_{\frac{1}{2}} = 10 m i n)$ & B $(t_{\frac{1}{2}} = 20 m i n)$ follow I order kinetics in such a way that $[A]_{i} = 8 [B]_{i}$ . Time when $[B] = 2[A]$ in min is:

Options:

Answer:

Solution:

For A:

$8 a \overset{10}{\to} \overset{10}{\to} \overset{10}{\to} \overset{10}{\to} \overset{10}{\to} \overset{10}{\to} \overset{10}{\to} \overset{10}{\to} \frac{a}{32}$

For B:

$a \overset{20}{\to} \overset{20}{\to} \overset{20}{\to} \overset{20}{\to} \frac{a}{16}$
