Energy overall

It has a higher boiling point, so it exists as a liquid at room temperature. Pentane has more sites along its length than methane does where temporary dipoles can form. The dispersion forces add up, so that it takes more energy overall to separate the molecules. This leads to a higher boiling point. [Pg.420]

The small S-T splitting in Ceo and C70 ( 10kcal/mol in Cgo, [18,23] 7.0 kcal in C70 [33]) is probably a result of the large diameter of the molecules and the resulting small electron-electron repulsion energy. Overall, the behavior of C70 is similar to that of Ceo. but the lower symmetry relaxes the forbiddenness of some absorption and emission processes. [Pg.351]

Energy Overall specific energy per ton of ethylene range from 3,000 kcal/kg to 6,000 kcal/kg, depending on feed type and battery limit conditions. [Pg.144]

The Rates of Reaction simulation (eChapter 14.2) allows you to adjust activation energy, overall energy change, temperature, and starting concentration of a reactant to assess the effect of each variable on initial reaction rate. [Pg.573]

In this notation, Eq is our zero-order energy, and the primes indicate corrections to be added to the zero-order value. Thus, E[ is the first-order correction to the energy, 2 is the second-order correction, and the second-order energy, overall. [Pg.165]

Two other systems were also examined, norbomene and 1-cyclopentene-1-carboxylic acid. Norbomene, where the model is 2-butene, exhibited a similar trend with little substituent effect, although the strained model leads to a high 7t, 7T triplet energy. Overall, the mod,MP2 prediction of 72.5 kcal mol is corrected by 0.9 kcal mol" for substituent effects and 3.1 kcal mol " for correlation effects, leading to the G2MS MP2 value of 76.5 kcal mol , which is about 3 kcal mol " higher than experiment. The... [Pg.1252]
