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} 94239Pu+01n→56144Ba+3893Sr+301nWhich statement about this reaction is not true?
The total binding energy of 94239Pu^{239}_{94}\text{Pu}94239Pu is less than the total binding energy of 56144Ba^{144}_{56}\text{Ba}56144Ba.
3893Sr^{93}_{38}\text{Sr}3893Sr has a higher binding energy per nucleon than 56144Ba^{144}_{56}\text{Ba}56144Ba.
The mass of a single 94239Pu^{239}_{94}\text{Pu}94239Pu nucleus is greater than the sum of the masses of a 56144Ba^{144}_{56}\text{Ba}56144Ba nucleus, a 3893Sr^{93}_{38}\text{Sr}3893Sr nucleus, and two free neutrons.
The total binding energy of the product nuclei is greater than the total binding energy of the reactant nucleus.
