Question: Consider a first order decomposition process $ A_3\to \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 decomposed is
Options:
A) 75%
B) 50%
C) 40%
D) 30%
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ A_3\to \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. $ % of A.
