Ideas of Quantum Chemistry P93 shows how quantum mechanics is applied to chemistry to give it a theoretical foundation. The structure of the book (a TREE-form) emphasizes the logical relationships between various topics, facts and methods. It shows the reader which parts of the text are needed for understanding specific aspects of the subject matter. Interspersed throughout the text are short biographies of key scientists and their contributions to the development of the field. | 886 15. Information Processing - the Mission of Chemistry c is independent of external conditions d is the least stable structure appearing in equilibrium conditions. 3. A molecular library composed of the associates of the molecules A and B represents a a mixture of the complexes AB b a mixture of all possible complexes of the A and B species c the complete physicochemical characterization of A and B d a mixture of all An Bn. 4. The self-organization of molecules is the spontaneous formation of a molecular complexes only in equilibrium conditions b a structure with minimum entropy c a structure with maximum entropy d complexes of molecules with synthons. 5. In the iterative solution of the logistic equation xn i Kxn 1 xn a there is a fixed point at any K b at any attempt to increase of K we obtain a bifurcation c some values of K lead to chaotic behaviour d at no value of K do we have extinction of the population. 6. In the Brusselator without diffusion the stable focus means a monotonic decreasing of the fluctuations x and y b dumped oscillations of the fluctuations x and y c non-vanishing oscillations of the fluctuations x and y d a limit circle. 7. In the thermodynamic equilibrium of an isolated system a the entropy increases b we may have a non-zero gradient of temperature c we may have a non-zero gradient of concentration d no dissipative structures are possible. 8. The bifurcation point for the number of solutions of x2 px 2 0 corresponds to a p 2 2 b p 1 c p 1 d p V2. 9. An event has only four possible outputs with a priori probabilities pi p2 p3 p4 4. Reliable information comes that in fact the probabilities are different pi p2 1 p3 1 p4 1. The information had Ii bits and Ii is equal to a 1 bit b 0.5 bit c 2 bits d 0.25 bit. 10. The situation corresponds to Question 9 but a second piece of reliable information coming says that the situation has changed once more and now p1 p2 0 p3 0 p4 2. The second piece of information had I2 bits. We pay for information
