A3 longrightarrow (3/2) A2 A-x (3/2) x A-x=(3/2) x or x=(2/5) A=40 % of A .

Q. Consider a first-order decomposition process
$A_{3} ⟶ \frac{3}{2} A_{2}$

A plot of concentration of $A_{3}$ and $A_{2}$ versus time is shown below. At time $t_{A}$ percentage of reactant composed is

$75%$

$50%$

$40%$

$30%$

$A_{3} ⟶ \frac{3}{2} A_{2}$

$A - x \frac{3}{2} x$

$A - x = \frac{3}{2} x$

or $x = \frac{2}{5} A = 40%$ of $A .$
