Slope, line

The operating lines begin on the x-axis at Xb and Xq. Both slopes are [(LA/ )-lJ. The rectifying line slope will come out negative and the stripping positive.

The constant is called the modulus of elasticity (E) or Young s modulus (defined by Thomas Young in 1807 although the concept was used by others that included the Roman Empire and Chinese-BC), the elastic modulus, or just the modulus. This modulus is the straight line slope of the initial portion of the stress-strain curve, normally expressed in terms such as MPa or GPa (106 psi or Msi). A... 

Case II. ai3 > oti2- In this case, the tie lines slope toward the 1-3 binary line. This could have been intuitively predicted by considering the limiting case of an immiscibility band across the phase diagram, as shown in Fig. 31C. Of necessity, the tie lines become parallel to either the 1-3 or the 2-3 binary lines in the limit of pure 1-3 binary or pure 2-3 binary, respectively. 

Case III. a13 < oc12. (See Fig. 31D.) Following consistently the explanation of Case II, the tie lines slope toward the 1-2 binary line. In general, then, the effect of the relative values of the 1-2 and 1-3 Margules parameters is to cause the tie lines to slope toward the least ideal of these two binaries. 

The criteria which would be most desirable for industrial application of a separation process involving a supercritical gas may be established by comparing Figs. 3IB, 3ID, and 32. The largest cost in such a process is likely to be that of gas compression. Therefore, the maximum separation possible of the two solvents should occur for the addition of a given amount of gas, and the total pressure required to dissolve this gas should be small. This is the case if the tie lines slope toward the 1-3 binary line and if the gas is readily soluble. In terms of the Margules parameters and Henry s constant, these favorable criteria are ...

Draw and label the axes and mark a horizontal line at a pressure of 23 mmHg to represent the constant nc. Next draw a line sloping downwards from left to right from 35 mmHg to 15 mmHg to represent the falling capillary hydrostatic pressure (Pc). Area A represents the fluid filtered out of the capillary on the arteriolar side and area B represents that which is reabsorbed on the venous side. Normally these two areas are equal and there is no net loss or gain of fluid. 

It is important to stress that the relation between (Vn) and [l-Lc] is described by the straight line (slope equal 220 xm L/mol). Such dependence is possible only when the number of mierospheres in the reaction mixture is constant. Concentration of mierospheres ([mierospheres] expressed as number of mierospheres in 1 L of reaction mixture) can be calculated from equation ... 

Rapid Equilibrium Case. In the absence of significant amounts of product (i.e., initial rate conditions thus, [P] 0), the rate expression for the rapid equilibrium random Bi Uni mechanism is v = Uniax[A][B]/(i iai b + i b[A] + i a[B] + [A][B]) where is the dissociation constant for the EA complex, and T b are the dissociation constants for the EAB complex with regard to ligands A and B, respectively, and Umax = 9[Etotai] where kg is the forward unimolecular rate constant for the conversion of EAB to EP. Double-reciprocal plots (1/v v. 1/[A] at different constant concentrations of B and 1/v v. 1/[B] at different constant concentrations of A) will be intersecting lines. Slope and intercept replots will provide values for the kinetic parameters. 

S]/[M], a plot often called a CLD plot. Cs is the straight line slope of the CLD plot. Cm can he obtained from polymerizations at very low initiator concentrations and no chain-transfer agent present. The last term on the right side of Eq. 3-121 is zero, and the first term is very small. Under these conditions the slope of the CLD plot is Cm- Chain transfer constants obtained by the CLD method are essentially indistinguishable from those of the Mayo plot [Heuts et al., 1999]. 

Similar calculations were also performed in the strong segregation limit. In this case, the two-phase and disordered homogeneous regions were found to be smaller, and the phase boundaries were more vertical (see Fig. 6.49) (Shi and Noolandi 1995). This phase diagram was interpreted on the basis of interfacial curvature. If the diblocks are completely segregated, the phase boundaries are determined by the total composition / (=

Broken-line graphs illustrate a measurable change over time. If a line is slanted up, it represents an increase, whereas a line sloping down represents a decrease. A flat line indicates no change as time elapses. 

Bronsted plots with some scatter should always be examined carefully because they might conform with the Eigen equation. A classic case is the acid-catalysed reaction of aniline with HNCO which can be fitted to a shallow Bronsted line (slope = —0.19)[9] however, the data are also consistent with an Eigen dependence (Fig. 11.5B) arising from a mechanism involving trapping of an addition intermediate by proton transfer (Scheme 11.11).
