... Potassium dichromate is a readily available and inexpensive reagent. The catalytic effects of several Lewis acids upon the activity of this oxidant were thoroughly studied. For this purpose the oxidation of benzhydrol to benzophenone was investigated in the presence of AlCl3, FeCl3, BiCl3, NiCl2, Ce ...

What is equilibrium?
... • A reaction is at equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. • The equilibrium constant expression is a ratio of the molar concentrations of the products to the molar concentrations of the reactants with each concentration raised to a power equal to i ...

... X-ray crystallographic studies established the molecular structure of 4 (Fig. 2) providing further conrmation that the direct C4 zincation of 3 has successfully been accomplished with the retention of the original Zn–Ccarbene bond. Exhibiting a solvent-separated ion pair structure, 4, contains an o ...

... In this experiment, the flux at the electrode (i.e., the rate of the electrode reaction, thus the current), depends on the diffusion rate only (i.e., depends on the mass transfer only). According to the First Fick law, the rate of diffusion depends on the diffusion coefficient (D) and the concentrat ...

... reaction proceeds from left to right in order to regain eq. Addition of more solid BaSO4 or BaO will have no effect on the eq. because concentrations of pure solids are not included in the eq. constant expression. If total pressure is altered, the numerical value of K is not changed. The only factor ...
