Units for the gas constant vary, depending on other units used in the equation. Value of the Gas Constant The value of the gas constant R depends on the units used forpressure,volume, and temperature. Before 2019, these were common values for the gas constant. R = 0.0821 liter·atm/mol...
Evaluated kinetic and photochemical data for atmospheric chemistry: Volume I - gas phase reactions of ceO_x, ceHO_x, ceNO_x and ceSO_x species This article, the first in the series, presents kinetic and photochemical data evaluated by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for ...
Figure 4. The volume and temperature are linearly related for 1 mole of methane gas at a constant pressure of 1 atm. If the temperature is in kelvin, volume and temperature are directly proportional. The line stops at 111 K because methane liquefies at this temperature; ...
The study was undertaken to determine the effect of dipicrylethane, a common impurity in HNS,on the volume of volatiles evolved during HNS vacuum stability measurements,and to evaluate the repeatability of results obtained during this testing.

Since a built-in water storage tank was used, the volume of free space in the adsorption tank did not change during the whole process of wetting the pulverized coal. Therefore, the increase in gas pressure in the adsorption tank was caused solely by the increase in gas volume, which could...
Comments & OpinionOpen Access01 Jul 2021Communications Chemistry Volume: 4, P: 102 In the loop Photocatalytic conversion of methane to ethane suffers from low yields due to poor selectivity and quantum efficiency. Now, ethane is produced by a photochemical looping strategy using a nanocomposite of ...
Nature Catalysis volume 3, pages 843–850 (2020)Cite this article 4848 Accesses 16 Altmetric Metrics details Abstract Industrially, aldehydes are produced annually on a multimillion-tonne scale via the hydroformylation of olefins with syngas (CO/H2 mixture). Nonetheless, this transformation has not ...
In three-phase systems, where the liquid constitutes the continuous phase, solid is the catalyst and gas represents the dispersed phase, there are decisive criteria which have to be observed in reactor design. These are e.g. the interfacial area per unit volume between gas and liquid, the vol...
Since this thermal modulation occurs on-column in a short section of fused capillary, the concentration pulses that it generates are of appropriate volume irrespective of column dimensions. Extra-column band broadening is also minimized because there are no mechanical parts, and no sample transfer is...
