Energy factor

Before we proceed to discuss energy changes in detail it is first necessary to be clear that two factors determine the stability of a chemical system—stability here meaning not undergoing any chemical change. These two factors are the energy factor and the kinetic factor,... [Pg.62]

Based on known ocpcrimontal AG values, and Q, were estimated. The system phenol-HMPA in CCI4. was chosen as the reference standard the H-boud free energy factors C, and Q were set at -2.50 (phenol) and 4,00 (HMPA) respectively. [Pg.430]

Energy factor is a measure of average service efficiency at a specified condition and hot water draw pattern. It includes the effects of both standby losses and rccnvei y efficiency of the water heater. Currently, water heaters are shipped from the manufacturers with thermostats set at 120°F (48.9°C) to reduce the risk of scalding. This is a drop from values of 140°F (60°C) that were reported from the early 1970s. [Pg.1216]

E s are the unperturbed energies of the electronic and vibrational states, respectively, and Bm is a constant energy factor which depends on the M excited state. It appears from Eq. (6.5) that ungerade symmetry of inverse energy mismatch between the relevant levels. [Pg.94]

How much the energy factor favors the crystal depends upon the change in heat content as a mole of solid dissolves. This change is called the heat of solution. The heats of solution of iodine in these two solvents have been measured they are as follows ... [Pg.166]

We see that there is a much greater energy rise when a mole of I2 dissolves in CCU than when a mole of I2 dissolves in alcohol. Thus the energy factor (favoring the crystal) that opposes the randomness factor (favoring solution) is much... [Pg.166]

Studies of photoelectrochemical phenomena are of great theoretical value. With light as an additional energy factor, in particular, studies of the elementary act of electrochemical reactions are expedited. Photoelectrochemical phenomena are of great practical value as well. One of the most important research activities nowadays is development of electrochemical devices for a direct conversion of luminous (solar) into electrical energy and photoelectrochemical production of hydrogen. [Pg.557]

Phenol and hexamethylphoshoramide (HMPA) were selected, respectively, as the standard H-bond donor and H-bond acceptor with their values fixed on free energy and enthalpy H-bond scales for phenol, -2.50 for the H-bond donor enthalpy factor (TJ and also for the H-bond donor free energy factor (Ca) for HMPA, 2.50 for the H-bond acceptor enthalpy factor ( J and 4.00 for the H-bond acceptor free energy factor (CJ. [Pg.132]

The satisfactory correlations between Kamlet-Abraham s acidity parameters and H-bond donor free energy factors, and between Kamlet-Abraham s basicity parameters and H-bond acceptor free energy factors for many sets of compounds [26] deserve particular mentioning ... [Pg.133]

Displacements of lattice members are determined by energy factors and concentration gradients. To a considerable extent, diffusion in solids is related to the existence of vacancies. The "concentration" of defects, N0, (sites of higher energy) can be expressed in terms of a Boltzmann distribution as... [Pg.279]

Besides the energy factors, defined by the close-packing principle, entropic factors are also involved in determining the mode of packing of molecules. A molecule in a crystal tends to maintain part of its symmetry elements, provided that this does not cause a serious loss of density. In a more symmetric position a molecule has a greater freedom of vibration, that is, the structure corresponds to a wider energy minimum.126... [Pg.110]

The normal operation shall not be capable of igniting the hazardous environment when adjusted for its worst operating conditions and an additional energy factor of 1.5 is introduced ... [Pg.257]
