Question: For the reaction: N2(g) + 3H2(g) = 2NH3(g) +91.8 kJ state the direction of the equilibrium shift (if any) in each of the following cases, and give your reasoning: (a) The total pressure is decreased at constant te...
N2(g)+3H2(g)⇋2NH3(g)Kp=5.8\times105 and given the partial pressures of N2(10atm),H2(10atm)and NH3(5atm),calculate Q and compare it to Kp. Will the reaction shift to the left or the ...
The cross-section for the charge-transfer reaction of O− with O2 is determined in the relative kinetic energy range from 1 eV (threshold) to about 3 eV, using a combination of experimental and theoretical ion-swarm techniques. Reaction rate constants are measured in a helium-buffered flow-...
For reaction (2), CF3O radicals are prepared by another source: the thermolysis of the dimer CF3OOCF3 and the derived rate constant is k2 = (4.7 ± 0.9) × 1011 cm3 molecule1 s1. Our results are in reasonable agreement with recent measurements using different techniques. 展开 DOI: ...
(CO + H2). This catalyst is also applied to methanol synthesis from CO2hydrogenation. However, Cu/ZnO/Al2O3is also an active catalyst for the RWGS reaction, resulting in a low methanol selectivity. Moreover, CO2hydrogenation produces more water, which causes severe sintering and ...

The reaction sequence that converts molecular nitrogen into nitrogen oxides involves sequential recombination of N2 with H atoms: N2→NNH→N2H2→N2H3. N-N bond cleavage occurs in the reaction of N2H3 with H2 forming NH3 and NH2; These last species are oxidized mainly in the sequence NH3→...
In addition, on the basis of in situ DRIFTS, kinetic measurements, and DFT calculation results, we discovered that the NH3-SCO reaction over Ag/nano-Al2O... 展开 关键词: N2− mechanism reaction pathway low-temperature oxidation Ag/Al2O3 ammonia (NH3) ...
Finally, ∆Gmax-NH3 < ∆Gmax-N2O, ∆Gmax-NH3 < ∆Gmax-N2 and ∆Gmax-NH3 < ∆Gmax-H2 (∆Gmax-N2O/N2/H2 is the maximum Gibbs free energy change of hydrogenation steps for N2O/N2/H2 synthesis via the corresponding most favorable reaction mechanism) are adopted to...
prevents it as a reactive form and thus demands a significant amount of the global energy cost annually2. In addition, the use of fossil fuels to produce H2reactant also leads to a significant level of CO2release3. The electrochemical N2fixation (also known as N2reduction reaction, N2RR) ca...
