14 sie 2020 · Because H 2 is a good reductant and O 2 is a good oxidant, this reaction has a very large equilibrium constant (K = 2.4 × 1047 at 500 K). Consequently, the equilibrium constant for the reverse reaction, the decomposition of water to form O 2 and H 2, is very small: K′ = 1 / K = 1 / (2.4 × 1047) = 4.2 × 10 − 48.

23 cze 2023 · Solution. According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.
10 sie 2021 · Co(OH) 2 @NC polyhedron performs more excellent activity and durability compared with noble metal catalysts. In particular, Co(OH) 2 @NC presents excellent OER and ORR catalytic activity by virtue of its unique structure, high porosity and the synergistic catalysis between Co(OH) 2 and nitrogen-doped carbon.
30 sty 2023 · the equilibrium constant expression is written as. (7)K = ad D. *The lower case letters in the balanced equation represent the number of moles of each substance, the upper case letters represent the substance itself. If K> 1 then equilibrium favors products. If K <1 then equilibrium favors the reactants.
