Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3 KCl + NaClO 3 → NaCl + KClO 3. It can also be produced by passing chlorine gas into a hot solution of caustic potash: [8] 3 Cl 2 + 6 KOH → KClO ...
The photochlorination of hydrocarbon is unselective, although the reactivity of the C-H bonds is tertiary>secondary>primary. At 30 °C the relative reaction rates of primary, secondary and tertiary hydrogen atoms are in a relative ratio of approximately 1 to 3.25 to 4.43.
Potassium hypochlorite is produced by the disproportionation reaction of chlorine with a solution of potassium hydroxide: [2] Cl 2 + 2 KOH → KCl + KOCl + H 2 O. This is the traditional method, first used by Claude Louis Berthollet in 1789. [3] Another production method is electrolysis of potassium chloride solution.
The rate of predation upon the prey is assumed to be proportional to the rate at which the predators and the prey meet; this rate is evaluated as xy, where x is the number of prey, y is the number of predator. This is a typical example of the law of mass action.
where A and B are reactants C is a product a, b, and c are stoichiometric coefficients,. the reaction rate is often found to have the form: = [] [] Here is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the ...
Additionally, these ionic liquids have high polarity and their ability to solubilize organic and inorganic molecules leads to enhanced reaction rates, which makes them more desirable. Many experiments found that ionic liquids with N-halosuccinimides as the solvent were an effective, greener alternative to conventional solvents. [ 6 ]
a thermodynamic equilibrium constant, denoted by , is defined to be the value of the reaction quotient Q t when forward and reverse reactions occur at the same rate. At chemical equilibrium , the chemical composition of the mixture does not change with time, and the Gibbs free energy change Δ G {\displaystyle \Delta G} for the reaction is zero.
The rate of hydrolysis is slow enough to allow the extraction of Cl 2 O with organic solvents such as CCl 4, [3] but the equilibrium constant ultimately favours the formation of hypochlorous acid. [7] 2 HOCl ⇌ Cl 2 O + H 2 O K (0 °C) = 3.55x10 −3 dm 3 /mol
