Question
A nuclear reaction has a reaction energy Q = -14.07 MeV. Which conclusion about the masses of the reaction components can be reached? Let 931.5 MeV = 1 u.
The reaction involves a mass increase of 0.01510 u.
The reaction involves a mass defect of 0.01510 u.
One of the particles that enters into the reaction has a mass of 0.01510 u.
One of the particles that is produced by the reaction has a mass of 0.01510 u.

Explanation / Answer
Since Q = -14.07 MeV = -14.07/931.5 = - 0.01510 u
Hence this reaction involves a mass defect of - 0.01510 u.
