Examples of graphs 1. What do we mean by Rate and how is it measured? The phrase ‘rate of reaction’ means ‘how fast is the reaction’ or 'the speed of the reaction'. It can be measured as the 'rate of formation of product' (e.g. collecting gaseous product in a syringe) or ...
A chemistry research paper investigated the reaction rate of a new compound. The researchers altered the temperature, pressure, and concentration of the reactants. They found that when the temperature was raised to 30 degrees Celsius, the reaction rate doubled compared to when it was at 20 ...
Design and Implementation of an Educational Game for Teaching Chemistry in Higher Education New paradigms in education have led to a need for alternative methodologies in the higher education classroom. An educational game on molecular geometry, p... M Antunes,MAR Pacheco,M Giovanela - 《Journal ...
The coefficient k in the reaction rate equation is the rate constant (as in Eq. (2)). This rate constant is changed by temperature, but not by the concentration of the species involved in the reaction. In the rate equation, the units of k are always used as a conversion factor for ...
To understand the molecular origins of epistasis, we studied the reaction kinetics of the OXA-48 variants (Fig. 2a). We monitored the conversion of CAZ by wtOXA-48, F72L and Q4 using a stopped flow and discovered that all enzymes catalysed the conversion of CAZ with an initial activity bu...
Human islet amyloid polypeptide (hIAPP) self-assembles into amyloid fibrils which deposit in pancreatic islets of type 2 diabetes (T2D) patients. Here, we applied chemical kinetics to study the mechanism of amyloid assembly of wild-type hIAPP and its mor
In this sense, the NCI index identifies interactions in a chemical system solely based on the electron density, and its derivative was given by Equation (1). A graphical index in 2D provides a characterization of this interaction [58]. To further characterize the IHB in L1, and its ...
Past studies have shown that the rate of blockade by the reagents is typically a better indicator of pore-lining residues that the degree of the steady-state block (Liu et al., 1997; McNally et al., 2009). Because the reaction rates of MTS reagents (~ 105 M− 1 s− 1) and Ag...
