Reactions steady increase with extent

Hence the weight/number ratio of chain lengths in these systems undergoes a steady increase with extent of reaction, approaching an ultimate value of 2. 

As the pressure in the reaction vessel increases, the mean free path of the gaseous molecules will decrease and the ease with which radicals can reach the surfaces of the vessel will diminish. Surface termination processes will thus occur less frequently fst will decline and may do so to the extent that fst + fgt becomes equal to fb oc — 1). At this point an explosion will occur. This point corresponds to the first explosion limit shown in Figure 4.1. If we now jump to some higher pressure at which steady-state reaction conditions can again prevail, similar... 

Conventional kinetic analysis of the reactions of NM, nitroethane (NE), and 2-nitropropane (2-NP) with hydroxide ion in water revealed that the reactions are complex and involve kinetically significant intermediates. The deviations from first-order kinetics were observed to increase with increasing extent of reaction and in the reactant order NM < NE < 2-NP. The apparent deuterium kinetic isotope effects for proton/deuteron transfer approach unity near zero time and increase with time towards plateau values as the reaction kinetics reach steady state. 

A slight increase in temperature led to a significant reduction of the reaction time (1.5 h at 40°C vs. 48 h at 20°C), which might to some extent be due to the different viscosities of the ionic liquid at these temperatures. After product isolation via distillation, reuse of the catalyst solution was feasible, but with a steady decrease in activity.
