Question

For a first order reaction, $n A \longrightarrow B$ whose concentration vs time curve is as shown in the figure. If half life for the reaction is $24$ minutes. Find out the value of $n$.

Answer 1

and At $48\, \min a-n x=x$
$\therefore \frac{\ln 2}{24}=\frac{1}{48} \ln \frac{a}{(a / n+1)}$
$4=n+1$
$n=3$
