A) \[Y\to 2Z~\]
B) \[W\to X+Z\,\]
C) \[W\to 2Y\]
D) \[X\to Y+Z\]
Correct Answer: C
Solution :
[c] Energy is released when stability increases. This will happen when binding energy per nucleon increases.| Reactant | Product |
| Reaction [a] \[60\times 8.5\,MeV\] \[=510\,MeV\] | \[2\times 30\times 5\] \[=300\,MeV\] |
| Reaction [b] \[120\times 7.5\] \[=900\,MeV\] | \[(90\times 8+30\times 5)\] \[=870\,MeV\] |
| Reaction [c] \[120\times 7.5\] \[=900\,MeV\] | \[2\times 60\times 8.5\] \[=1020\,\,MeV\] |
| Reaction [d] \[90\times 8\] \[=720\,\,MeV\] | \[(60\times 8.5+30\times 5)\] \[=600\,MeV\] |
