Question

Figure shows a roughly approximated curve of binding energy per nucleon with mass number. $W,X,Y$ and $Z$ are four nuclei indicated on the curve. According to this curve, the process that would release energy is:

• A. $Y\to 2Z$
• B. $W\to X+Z$
• C. $W\to 2Y$
• D. $X\to Y+Z$

Answer 1

The correct option is C $W\to 2Y$

Energy is released in a process when the binding energy per nucleon of the product is more than that of initially reacting elements. Hence, option (c) is correct.
