Rate minima in steady state reactions depending on substituent constants cannot be easily explained by single route conventional mechanisms even after considering nonlinear steps. Such cases are conventionally explained by a switch in reaction mechanisms. An alternative developed in this study assumes ...
Therefore, a process could be from a classical reaction-driven system to an evolving system with no chemical transformation involved, like a chromatographic elution, a blending process, or a conformational or polymorphic transition. In all these systems, the concentration profiles are never a set of...
For a chemical reaction, variation in concentration [A] vs time (s) plot in given below: i) Predict the order of the reaction. ii) What does the slope of the line and intercept indicate ? iii) What is the unit of rate constant(k)? View Solution For a chemical reaction R → ...

As the formic acid concentration within the solid electrolyte layer gets higher and higher, the Faradaic efficiency (FE) is dramatically decreased due to the potentially increased reverse reaction rate, as well as the increased crossover to the anode as frequently observed in fuel cells47,48. ...
aThe degree of inhib-itive effect was almost the same for ethyl acetate and amyl acetate in this concentration range. The half-saturation constant Ks values of ethyl acetate and amyl acetate were 16.26 and 12.65 ppm, respectively. The maximum reaction rate Vm values of ethyl acetate and amyl ...
If the reaction rate is slow\(,\) Z >> 1 (or Da << 1), and the combination of aggregate diffusion and movement of the inclusion body has time to make the concentration field uniform (i.e., these factors prevent a stable concentration gradient from forming around the inclusion), then ...

This indicates that the oxygen reduction reaction is stronger at the steel surface toward the anode, and it will produce more OH−. As the time increases, the rise in the OH− concentration reduces the rate of the oxygen reduction reaction at the steel surface. Hence, the local current ...
(2010)). A higher temporal resolution and a lower detection threshold can be performed by proton transfer reaction PTR (e.g. Feilberg et al. (2010b)) or the selected ion flow tube mass spectrometry (SIFT-MS) (e.g. Heynderickx et al. (2013)). All these measuring methodologies provide...
