CaNis curves

Equality between the 1, 2 wave function and the modulus of the 2, 1 wave function, v /(j2, i), shows that they have the same curve shape in space after exchange as they did before, which is necessary if their probable locations are to be the same. The phase factor orients one wave function relative to the other in the complex plane, but Eq. (9-17) is simplified by one more condition that is always true for particle exchange. When exchange is canied out twice on the same particle pair, the operation must produce the original configuration of particles... 

Use the F t) curve generated in Illustration 11.1 to determine the fraction conversion that will be achieved in the reactor if it is used to cany out a first-order reaction with a rate constant equal to 3.33 X10 s . Base the calculations on the segregated flow model. 

In order that the material may follow the curve in Fig. 6.23b, it is necessaiy for the critical fibre volume to be exceeded. The critical fibre volume is defined as the volume of fibres which, after matrix cracking will cany the load which the composite sustained before cracking. In such a way, a brittle material in which one cracking surface could be formed with low energy, transforms into the pseudo-plastic body, which can cany momentaiy the overioad with no visible damage. Therefore, the... 

It was shown that the determination of the diffusion coefficient was to cany on the final stage of the swelling kinetic cnrve, which was described by a universal asymptotic expression [6.6.6]. The initial stage of the kinetic curve for this is of httle use, because it is not possible to obtain a sufficiently accurate and simple analytical expression. 

To cany out quantitative research, the isothermal rate curves must be plotted for separate values of the concentration being studied. The isolation method must be used so the other reactant concentrations are kept constant during the reaction. 

From this relationship, we can show that if the initial and B ions are oppositely charged, the curve In ko versus 1/D (at zero ionic strength) is a straight line with a negative slope whereas it is positive slope if the ions cany charges of the same sign.
