Question 13 – Radioactivity (A-level only) - Questions

An induced fission reaction of plutonium-239 can be represented by the following equation:

$94239Pu+01n→56144Ba+3893Sr+301n^{239}_{94}\text{Pu} + ^{1}_{0}\text{n} \rightarrow ^{144}_{56}\text{Ba} + ^{93}_{38}\text{Sr} + 3^{1}_{0}\text{n}$

Which statement about this reaction is not true?

The total binding energy of $94239Pu^{239}_{94}\text{Pu}$ is less than the total binding energy of $56144Ba^{144}_{56}\text{Ba}$ .

$3893Sr^{93}_{38}\text{Sr}$ has a higher binding energy per nucleon than $56144Ba^{144}_{56}\text{Ba}$ .

The mass of a single $94239Pu^{239}_{94}\text{Pu}$ nucleus is greater than the sum of the masses of a $56144Ba^{144}_{56}\text{Ba}$ nucleus, a $3893Sr^{93}_{38}\text{Sr}$ nucleus, and two free neutrons.

The total binding energy of the product nuclei is greater than the total binding energy of the reactant nucleus.
