Calculate the energy released by a reaction from binding energies |
If in U: Work out difference in mass between inputs and products (ensure that products have a smaller mass than inputs) Mass in u x 931.5 gives energy in MeV |
|
|
How much energy is released, in J, from 1 kg of reactant... questions |
Energy per unit mass, take the energy released and divide it by the mass of the nucleons (no. nucleons x 1.67x10^-27) |
|
|
Binding energy using the mass defect |
Keep all values in u untill very last part of question, then convert ∆m = (Z x mp) + (N x mn) - Melement ∆m = X u Binding energy = X x 931.5 = Y (MeV) |
