The extents xr for reactions with net positive rates and the extents xin are strictly increasing in batch and semi-batch modes. Proof: In absence of outlet, that is for uout = 0, (3a) reduces to x.r(t)=rv(t) and (3b) to x.in(t)=uin(t). It follows from rv(t)≥ 0R and...

The affinity of the net reaction is maintained at a constant value by the flows H2 and Br2. The affinity of the first reaction is unconstrained. Show that the stationary state leads to minimal entropy production. Solution: Assume that the system is homogeneous with a volume V = 1. The net...
Overall, our strategy represents a general method to create toughened covalently crosslinked polymer materials with simultaneous enhancement of mechanical strength and ductility, which is quite challenging to achieve by conventional chemical methods.
this study is to investigate the students' conceptions about the reaction rate changes during the chemical equilibrium shifts and also whether the questions about basic concepts of the reaction rate are helpful for the students' understanding of reaction rate changes during the chemical equilibrium ...
and NMR can be used for closed-loop optimization of reactions, exemplified using Van Leusen oxazole synthesis, a four-component Ugi condensation and manganese-catalysed epoxidation reactions, as well as two previously unreported reactions, discovered from a selected chemical space, providing up to 50%...
Fig. 1 shows the net fluxes of carbon atoms between the species at temperature T = 1810 K during the homogeneous adiabatic explosion of a lean, atmospheric methane–air mixture. By comparing flux diagrams at different temperatures, the change in chemistry during an explosion can be inspected. Th...
