Subject: Inorganic Chemistry · Chapter: Nuclear Chemistry · Topic: Nuclear Reactions Q Value · Exam: CSIR-NET 2014 · Marks: 2 · Difficulty: Medium
For a low energy nuclear reaction, ${}^{24}\mathrm{Mg}\,(\mathrm{d},\alpha)\,{}^{22}\mathrm{Na}$, the correct statements from the following are
(a)Kinetic energy of d particle is not fully available for exciting ${}^{24}\mathrm{Mg}$.
(b)Total number of protons and neutrons is conserved
(c)Q value of nuclear reaction is much higher in magnitude relative to heat of chemical reaction
(d)Threshold energy is $\leq$ Q value.
Answer
Explanation
The kinetic energy of the deuteron (d-particle) is very low, hence it cannot excite $^{24}\mathrm{Mg}$ nuclei.
