Question

Binding energy per nucleon versus mass number curve for nuclei is shown in the figure. A, B, C and D are four muclei indicated on the curve. The process that would release energy is

• A. $C\to 2D$
• B. $A\to C+D$
• C. $A\to 2C$
• D. $B\to C+D$

Answer 1

The correct option is A $C\to 2D$

We can clearly deduce from the graph that:

(A) $C>2D$

(B) $C>A\Rightarrow C+D>A$

(C) $C>A\Rightarrow 2C>A$

(D) $C>B\Rightarrow C+D>B$

Only in option A, the reactant side has more Binding energy than productant side thus releasing energy in the process.

Option (A) is correct.
