Chapter 18, Problem 20KT
Interpretation Introduction
Interpretation:
The key term corresponding to the definition “the minimum mass of a fissionable nuclide necessary to sustain a chain reaction” is to be stated.
Concept introduction:
Radioactive decay is the process that involves the emission of radiation by an unstable atomic nucleus. The atomic nucleus loses its energy. The process is spontaneous. The decay is accompanied by the emission of alpha particles, beta particles, and gamma rays. All the elements which have an

- Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NO2 (g) = N2O4(g) AGº = -5.4 kJ Now suppose a reaction vessel is filled with 4.53 atm of dinitrogen tetroxide (N2O4) at 279. °C. Answer the following questions about this system: Under these conditions, will the pressure of N2O4 tend to rise or fall? Is it possible to reverse this tendency by adding NO2? In other words, if you said the pressure of N2O4 will tend to rise, can that be changed to a tendency to fall by adding NO2? Similarly, if you said the pressure of N2O4 will tend to fall, can that be changed to a tendency to '2' rise by adding NO2? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO 2 needed to reverse it.
