Reactor selectivity
WebAug 15, 2024 · Heating the reaction gives poor endo/exo selectivity. However, upon addition of a Lewis acid (AlCl 3), the reaction can proceed at low temperature and th endo product is highly favored. Intramolecular Diels-Alder: the rules are breakable. Two types of connectivity for intramolecular Diels-Alder reactions exist: 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,

WebApr 9, 2024 · The electrochemical nitrogen reduction reaction (NRR) has the potential to replace the Haber–Bosch process for ammonia synthesis under ambient conditions. However, the selectivity and yield of the NRR are impractical, owing to the preferential binding of the electrocatalyst to H and the consequential coverage of active sites. WebDEFINITION The selectivity of a reaction is the ratio of the desired product formed (in moles) to the undesired product formed (in moles). OUTCOMES: Define and calculate the …
