Equilibrium constant (K-CP) for coordinative polymerization is measured for the first time. Constant K-CP is defined as [L](cp)/[M][L], where [L](cp) represents the concentration of the ligand present in the coordination polymer. Plot of absorbance changes measured for 3, a water-...
The length of time needed to achieve sedimentation equilibrium depends on the length of the solution column, the value of the reduced molecular weight, σ, and the diffusion constant. Because the time to reach equilibrium depends on the square of the column length, many cells and techniques ...
When 0.10 mol NO2 is added to a 1.0-L flask at 25 °C, the concentration changes so that at equilibrium, [NO2] = 0.016 M and [N2O4] = 0.042 M. What is the value of the reaction quotient before any reaction occurs? What is the value of the equilibrium constant for the reaction?
The oxidation of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate, catalyzed by glyceraldehyde 3-phosphate dehydrogenase, proceeds with an unfavorableequilibriumconstant, yet the flow through this point in the glycolytic pathway proceeds smoothly. ...
The acid-base behaviour of Loprazolam has been studied using an automated potentiometric titration system. The temperature was kept constant at 25 °C and the ionic medium was 0.1 mol dm −3 NaCl in different ethanol-water mixtures (5–20%). The values of the constants obtained at the ...
(b) At what value of t does the object first pass through the equilibrium position? Solution (a) We begin by determining the spring constant. Because the force F = 2 lb stretches the spring 3/2 in. × 1 ft./12 in. = 1/8 ft., k is found by solving 2 = k× 1/8. Hence k...
Specifically, we maintained a constant temperature difference while varying the duration of the preheating stage (indicated as t0 in Fig. 1c) to determine the quantity of liquid Se present in the precursor film. Furthermore, we compared the selenization processes involving solid-gas reactions with ...
What is the value of the equilibrium constant for the reaction between I2(s) and Br−(aq) at 25 degrees Celsius? Redox Reaction: A redox reaction involves two or more species undergoing changes in oxidation state, which in most cases involves different eleme...
To solve the problem, we need to find the partial pressure of water vapor at equilibrium for the given reaction: Na2HPO4⋅12H2O (s)⇌Na2HPO4⋅7H2O (s)+5H2O (g) Given:- Equilibrium constant Kp=31.25×10−13 Step 1: Write the expression for Kp The equilibrium constant Kp for the...
Oftentimes, one of the concentrations is kept constant by external controls or tight intracellular regulation, or its concentration vastly exceeds its Michaelis-Menten constant of the enzyme acting upon it. For these cases, Rottenberg (1973) also showed that the relationship between reaction rate and...
