Production volume increase numbering

As the production volume increases, total costs increase. However, as production increases, the total cost per unit tends to decline as fixed costs are spread out over a higher number of units produced. This phenomenon is called economy of scale. Economies of scale become apparent when the cost to produce a unit declines as the volume of production increases. If the cost per unit increases as volume increases, this is referred to as diseconomies of scale. 

In the reaction shown above, the volume of the reaction products (2 mol CO) is seen to be much greater than that of the reactants (2 mol of solid carbon plus 1 mol of oxygen). The effect of pressure on the free energy of formation of an oxide associated with an increase in the number of gas molecules which is representative of the type of reaction in the present illustration is shown in Figure 4.2 (A). Applying the criterion of volume increase per mole accompanying reaction at standard state to the case of metal oxidation such as... 

As would be expected, we find that a small number of materials account for the bulk of the production volume. In this case, those materials produced in excess of 100 million pounds per year represent only 1.8% of the total number of substances reported and account for 98.9% of the total pounds produced. Lowering the limit to 10 million pounds adds 2.7% of the chemicals, so we now have 4.5% of all the substances and we increase the total volume represented to 99.7%. Going further to one million, we find that only 9.5% of the materials account for 99.9% of the total production reported (Table I). 

Increased Frequency Reports. The requirement for increased frequency reports for serious expected ADRs with marketed products is revoked. This was also published in the Federal Register of 25 June 1997 (Volume 62, Number 122, pp. 34166-34168). The rationale for this was that despite receiving many such reports, only a small number of drug safety problems were identified. 

Ition of the ketone bodies may be as high as 5000 mg/24 hr, and the blood concentration may reach 90 mg/dl (versus less than 3 mg/dL in normal individuals). A frequent symptom of diabetic ketoacidosis is a fruity odor on the breath which result from increased production of acetone. An elevation of the ketone body concentration in the blood results in acidemia. [Note The carboxyl group of a ketone body has a pKa about 4. Therefore, each ketone body loses a proton (H+) as it circulates in the blood, which lowers the pH of the body. Also, excretion of glucose and ketone bodies in the urine results in dehydration of the body. Therefore, the increased number of H+, circulating in a decreased volume of plasma, can cause severe acidosis (ketoacidosis)]. Ketoacidosis may also be seen in cases of fasting (see p. 327). 

Changing Volume and Pressure Changing volume and/or pressure significantly impacts equilibrium reactions only when at least one of the reactants or products is a gas, because solids and liquids aren t compressible. Decreasing volume increases pressure. Therefore, decreasing the volume or increasing the pressure favors the smaller number of gas particles. Think of squeezing many gas particles into fewer gas particles, which offsets the increase in pressure. 

We need to determine the concentrations of each ion to calculate the ion product. There are a few things to keep in mind as we do this. First, when the two solutions are added together, the total volume increases to 0.10 L + 0.10 L = 0.20 L. Second, we need to determine the number of moles of each ion, and then calculate the molarity based on the new volumes.
