A variable in the Nernst equation is temperature, so the response (i.e. slope) of a pH electrode is dependent upon temperature. Therefore, pH measurements should be completed with an accurate measurement of temperature. The pH values of buffer solutions are temperature dependent and the response...
where kB is the Boltzmann constant (1.38 × 10−23 J/K), T is the temperature (293 K), and η is the viscosity of the solvent (0.001 kg m−1 s−1). The molecular weight of the protein was estimated by $${M}_{W}=\frac{4}{3}{R}_{h}^{3}\,\pi ...

Therefore, at a given temperature, the elevation of coral calcifying fluid pH is expected to negatively correlate with 1/βTA. This prediction is consistent with the trends observed in the experimental data. Regardless of the species they belong to, corals that grow in seawaters of similar tempe...
H2 is produced by bacteria through bio-process under ambient temperature and pH regimes, and the yield can be enhanced by the manipulation of other environmental conditions. The initial pH and temperature are the important factors that influence H2 production by bacteria. However, pretreatment methods...
The equation shows that the voltage generated is dependent on the acidity or alkalinity of the solution and varies with the hydrogen ion activity in a known manner. The change in temperature of the solution changes the activity of its hydrogen ions. When the solution is heated, the hydrogen io...
It was noticed that the rate constant of the reaction increases with increase in temperature for given concentration of AML (Table 2 and Figure 5). From the Arrhenius plot of log k/vs. 1/T activation parameters were computed (Table 2)....
A plot of experimental data of ln k vs 1/T might render a straight line with slope Ea/R (to determine Ea). As pigments stability is sensitive to temperature, Q10 values were calculate using Eq. (11).(11)Q10=k2k1where k1 and k2 are the constant rates at temperature T1 and T2 (T2...
kinetic measurement, pre-steady-state analysis allowed the determination of the pseudo-first order rate constant (kobs), characteristic of the formation of the complex, by fitting the decrease in the initial rate of the reaction (v0) to its steady-state rate (vs), according to Equation (1)...
CaCl2 was mixed with AX at room temperature and refluxed under stirring. All the concentrations (5, 10, 15% CaCl2 vs. 0.25 g of AX powder) resulted in gel formation by the interfacial complexation of Ca2+ ions. The swelling of CL-AX in deionized water (DW) was improved by increasing ...
