Atomic Structure Question 283
Question: A system irradiated for 10 min. is found to absorb $ 3\times 10^{18} $ quanta per sec. If the amount of substance decomposed is $ ~3\times {10^{-3}}mol $
$ (N_{A}=6\times 10^{23}) $ . The quantum efficiency of the reaction is
Options:
A) 2.5
B) 2
C) 1.5
D) 1
Show Answer
Answer:
Correct Answer: D
Solution:
- Quantum efficiency $ =\frac{Numberofmolesofsubstancereacted}{NumberofQuantaabsorbed} $
$ =\frac{3\times {10^{-3}}\times 6\times 10^{23}}{3\times 10^{18}\times 60\times 10}=1 $
