Equilibrium constant

Order Disorder Humans strive for a balance within their lives in order to demonstrate an equilibrium and security. In contrast, by expressing the laws of thermodynamics, it is stressed that through the process of discovering a balance, obstacles can be achieved. Thermodynamics highlights the stream of science attentive to heat and conversions to different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a…

Kidney stones are solid stone-like masses that form within the kidney and or the ureter. These solid masses are made up of salts and minerals commonly found in urine and are due to a constant build up of substances in the kidney. Depending on the size of the stone, ranging from as small as a grain of salt to as large as a golf ball, the stone may pass out of the body during urination or may get stuck in the bladder or the urethra. When kidney stones get stuck due to their large size, they may…

3.7. Equilibrium isotherms Langmuir isotherm proposed by Langmuir, (1918) with some limitations Dąbrowski, (2001) expressed as: (4) Where qm (mg g–1) is the maximum amount of the metal ion per unit weight of adsorbent, ‘qe’ is equilibrium adsorption capacity (mg g–1), ‘Ce’ is the equilibrium concentration of the adsorbate (mg L–1), and b is a constant which reveals the affinity of binding sites (L mg-1). From the plots between (Ce/qe ) and Ce the slope (1/qm ) and the intercept…

reaction shifted right and so did the E cell value. It got higher than the standard value as it attempts to reestablish equilibrium. According to LeChatliers principle, “When any system at equilibrium is subjected to change in concentration, temperature, volume, or pressure, then the system readjusts itself to counteract (partially) the effect of the applied change and a new equilibrium is established”. In the cell Zn (s) + Cu2+(aq) ↔ Zn2+ + Cu(s), as the concentration Cu2+ was increased…

isotherm data were analyzed and were fitted them into two models, Freundlich and Langmuir, because they are the most suitable and employed models. Equilibrium uptake of CV and MB was investigated with sorbent weight of 0.5 g of fennel seeds in contact with 100 mL of solutions and at pH 4 for CV and 6 for MB. The flasks were shaken at 200 rpm and the equilibrium concentration of the remaining CV and MB was determined by spectrometer. The analysis of the isotherm data is important to make…

A pendulum follows a very simple type of oscillation called “isochronous”, which means it always takes the same time. Therefore these are oscillations that always repeat in the same time period maintaining the same this constant time even with a change in amplitude. A simple pendulum follows this pattern and it is why it has been such an important element in clocks. This can also be applied in different gravitational field strengths as the motion of the pendulum will always take the same time…

adsorption equilibrium data were analyzed using Langmuir, Freundlich, Temkin and D-R isotherms. The sorption data was analyzed using linear form of all the isotherm equations Models having high correlation coefficient (R2 ) values are considered best fit to represent the sorption data. The Freundlich isotherm holds for multilayer non-ideal adsorption on heterogeneous surface and is represented by the following empirical equation: qe = KF Ce 1/n Where, KF = adsorption equilibrium constant…

Both titrations in this lab reflected these properties, such as acid-dissociation, acid-dissociation constants, etc. In parts A and B, it demonstrated the differences between strong and weak acids and why there is a significant difference between equivalence points, as one value was 7.21 and why the other was 8.38. Regardless that the pH differences are not…

This affects a decline in the aggregate curve in the same way: a decline in demand causes the curve to shift leftward, but the equilibrium level remains constant. This constant of price levels, or the aforementioned “sticky prices” is what causes the inflexibility. In the Keynesian model, the flexibility of price levels, most importantly wage levels, is what causes movement along both the demand and…

This clearly demonstrates that “sourcing” an exactly force-free macroscopic equilibrium with an equilibrium DF in a 1D cylindrical geometry is inherently a more difficult task than in the Cartesian case. The presence of “extra” positive definite inertial forces and, almost inevitably, forces associated with charge separation raises the question…
