Bond-Order Conservation-Morse Potential (BOC-MP) method is used to carry out the calculationon the CO2+ H20 system. One of the best catalysts for methanol synthesis in catalytic reductionof CO2 with H2O is Cu/ZnO/A1203 whose surface is supported by with some amount of Pd orGa. Reduction of CO2 with H20 on Cu will result in methanol formation; while on Ni will lead tomethane formation. In the me...

the oxidation of n-pentanol by tetramethylammonium fluorochromate in acidic solution wasstudied using spectrophotometric technique. the reaction was arranged to be under pseudo firstorderconditions respect to the oxidant. a michaelis-menten type kinetic was observed respect tothe substrate. the reaction is catalyzed by hydrogen ions. dependences of the reaction rates ontemperature and different...

A theoretical study of the kinetic and mechanism of intramoleccha cychcation of (1)-undeca-7,8-dien-2-yne was performed using MT methods at B3LYP and B3PW91 levels of theory using 6-311g, 6-311C.6-31 IGs*, 6-31I+G, 6-31 I4-SG and 6-3114H-Gs* basis seo. Equilibrium molecular geometries andharmonic vibrational frequencies of the reaccint, transition state and product wens calculated. Theconsidere...

A theoretical study of the kinetic and mechanism of 3-aug-Cope rearrangement in gas phase was performed usingDET methods at B3LYP levels of theory with 6-3114iG(d,p) bass set at 298.I5K. Equilibrium moleculargeometries and harmonic vibrational frequencies of the reactant, transition state Did product were calculated. Then,rate constant and activation thermodynamics parameters were calculated an...

a study of the kinetic analysis of total lead from spent car battery ash by hydrochloric acidleaching has been examined. the physico-chemical analysis of the ash powder was carried outby the inductively coupled plasma-mass spectrometry (icp-ms) and x–ray diffraction (xrd).the effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...
