Answer

Q value =231.08652 MeV

Work Step by Step

The reaction can be written as U235 +n ==> 140Ce+99Ru Total Mass Of Reactants = 238.05079 u+1.00866 u=239.05945 u Total Mass Of RProducts = 139.90543 u+98.90594 u=238.81137 u Mass defect = mass of reactants - mass of products = 0.24808u Q value = mass defect \times931.5 MeV =231.08652 MeV
