Interpretation: High desirability for development of nuclear reactors has to be explained.
Concept introduction: In a nuclear reaction, unstable nuclide disintegrates into stable nuclide with emission of various radiations spontaneously. It is called radioactivity of nucleus. These reactions are of 2 types: fission and fusion. Fission is process in which heavy nuclides disintegrate into lighter and stable ones. When 2 lighter nucleus come together to create a heavy nuclide, it is called as fusion.
Answer to Problem 45A
Since in
Explanation of Solution
The energy associated to nuclear fusion is many times higher than that for nuclear fisson. Even stars and sun produce their energy through fusion reactions. A fusion process of sun is as follows:
11H+11H→21H+01e+energy11H+21H→32He+energy32He+32He→42He + 211H + energy32He + 11H→42He+01e+energy
Due to availability of many light nuclei like 11H, 21H and 32He in abundance, huge efforts are being made to develop a fusion reactor. These light nuclei act as fuel in such reactors.
Since in nature, abundant amount of light nuclei are available, that act as fuel for fusion reactor and magnitude of high energy associated with fusion process than fission, development of fusion reactor is desirable.

- The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1arrow_forwardDon't used Ai solutionarrow_forwardIn an experiment, the viscosity of water was measured at different temperatures and the table was constructed from the data obtained. a) Calculate the activation energy of viscous flow (kJ/mol). b) Calculate the viscosity at 30°C.

The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
