  • The kinetics of ammonia oxidation over oxides of manganese, cobalt, copper, iron and vanadium have been studied. The proposed reaction mechanism involves oxygen adsorption (oxidation of the catalyst surface) and reduction of the surface with ammonia to form the reaction products.
  • Concentrated nitric acid acts as an oxidizing agent for both sulfur & carbon. In the case of sulfur, S will get the oxygen atoms & the water needed for the reaction: S+6HNO3→H2SO4+2H2O+6NO2 so if sulfur is converted to SO2 first, it will proceed into SO3 & eventually to H2SO4.
  • Zinc oxide react with sodium hydroxide to produce zincate sodium and water. This reaction takes place at a temperature of 500-600°C.
  • The overall reaction between acetic acid and ethyl alcohol over a sulphuric acid catalyst is as follows: CH3COOH + C2H5OH CH3COOC2H5 + H2O Acetic acid + ethanol ethyl acetate + water (A) (B) (C) (D) This reaction is reversible, exothermic and the equilibrium composition is a weak function of temperature.
  • when dilute HCl is added to Fe then Ferrous chloride ( FeCl2) and hydrogen gas (H2) will be formed.
