Kinetic-molecular theoiy

The Ideal Gas Law is derived from Kinetic Molecular Theoiy. Now that you have examined some gas laws, you can rephrase KMT and realize that ideally, gas molecules ... 

Which of these statements is not one of the principal assumptions of the kinetic-molecular theoiy for an ideal gas ... 

One of the important outcomes of the kinetic molecular theoiy is that the total kinetic energy of a mole of gas (any gas)js equal to iKT. With assumption 4 we saw that the average kinetic energy of one molecule is rrn2. For 1 mole of the gas we write... 

Simple collision theory does not provide a detailed interpretation of the energy barrier or a method for the calculation of activation energy. It also fails to lead to interpretations in terms of molecular structure. The notable feature of collision theoiy is that, with very simple means, it provides one basis for defining typical or normal kinetic behavior, thereby directing attention to unusual behavior. 

A chemical reaction is a complex process. Besides thermodynamic factors, the process has two other distinct aspects kinetic and molecular mechanistic ones. With the development of modem technology, more and more complex kinetic schemes can be determined by using sufficient experimental information and fairly general computer programs [155]. In order to proceed, it is useful to define what we mean by a theoiy of chemical reactions in the first place.

In the absence of a fiilly developed kinetic theoiy for liquids, the relationships lor molecular diflusion are usually assumed to parallel those for gases, although difliisivities ate often mote substantially dqiendeni on concentration of the diffusing components. In the case of equimolal courtterdifliision, die expression analogous to Eq. (7.1-20) is... 

The synthesis (Scheme 12.8) of the first [l2]collarene molecular belt (12.18b) was achieved in our laboratory through the repeated application of Diels-Alder (DA) cycloadditions between the dienophile 12.20 and the diene 12.21, which proceeds with extraordinarily high diastereoselectivity. While the DA reaction between 12.20 and 12.21 could, potentially, lead to four different diastereoisomeric products, only a single diastereoisomer was actually observed in this reaction. This especially high diastereoselectivity is dictated primarily by electronic effects, which kinetically favor attack on the diene 12.21 from the endo face, while attack on the dieneophile 12.20 is preferred from the exo side. Density functional theoiy (DFT) calculations (Figure 12.7) reveal that the observed diastereoselectivity has its cause in the selective stabilization of the endo-exo transition state (12.19a).
