Question

In the figure, a graph of average binding energy per nucleon against atomic mass number is shown. In which one of the following reactions will energy be produced?(a) Y —> 22 (b) W —> 2Y [Ans: Reaction(b)]

Answer 1

reaction b is teh anawer

Answer 2

Answer:

The reactions will be produced by w > 2Y

Option B

Explanation:

Binding energy per nucleon is dependent on the neutron-proton ratio. The neutron-proton ratio is dependent on placing the nucleus of an atom in a stable position. Neutron-proton ratio between 1 to 1.5 will be stable for most of the atoms.

In the graph, we can see that neutron-proton ratio of Y is most stable. Then, the nucleon binding energy decreases. So, the point W should be greater than W > 2Y
