WebMar 9, 2024 · Selectivity is typically achieved through chemical approaches. Recently in Nature, Yu, Lin, and co-workers disclosed an electrochemical carboxylation of N -heteroarenes with site selectivity tunable through reactor configurations. Using divided and undivided cells, they achieved C5- and C4-carboxylations, respectively, of 2-arylpyridines. WebUse sliders to vary the activation energy of each reaction and the isothermal reactor temperature to determine how selectivity and moles of products and reactants change …

Webflow rate entering the reactor by (CD4-107) where X is the number of moles of A reacted per mole of A entering the reactor, and is defined by (CD4-108) The molar flow rate of A within the reactor is (CD4-109) (CD4-110) (CD4-111) These equations for concentration are substituted into the rate law, WebThis difference in selectivity between light and dark is a strong indication of the contribution of a non-thermal effect to the reaction upon illumination. The rate-determining step for CO production is the desorption of CO from the catalyst, while for methanation this is the dissociation of the C-O bond, followed by hydrogenation to CH 4 [ 56 ]. WebMar 15, 2024 · When comparing at different reaction temperatures, it can be seen that the selectivity to isobutylene is higher under MWH . At yields around 25%, the selectivity is more than 30 points higher under MWH (28.7% yield to isobutylene with 76.5% selectivity compared to 25.3% yield to isobutylene with 45.8% selectivity under CH at the same … sunova nz
