Temperature dependence of the standard Gibbs free energy change for the reaction 2Li + 1/2O2 = 2Li+ + O2− in molten LiCl-KCl mixtures; LiCl:KCl = (a) 58.5:41.5 (eutectic), (b) 65:35, (c) 70:30, and (d) 75:25 mol% containing 0.5 mol% Li2O. (Error values denote 95% ...
where R is the gas constant, and the Gibbs Free Energy change of reaction per mole of product ΔGR in kJ/mol and the reaction equilibrium constant K are given by: (54)ΔGR=∑svsΔGf s K=∏s(nf sPP⊘∑snf s)vs In order that the chemical equilibrium condition be obeyed,...

The Gibbs energy change of solid state reaction of CaAl_4O_7 + 4Al_2O_3 = CaAl_(12)O_(19) was determined by electrical conductivity measurements. This technique is very useful to apply the reaction between the oxides of main group metal elements because the reaction does not exhibit an...
Trexel adds chemical foaming agent to its product line In terms of processing, it means that additional heat is needed to finish the vulcanization because the material will absorb energy to complete the endothermic reaction prior to vulcanization. Vulcanization of EPDM rubber compounds with and without...
This raises the intriguing question of how an ostensibly small chemical modification (conversion of sulfihydryl to sulfenyl), that is located at a significant distance from the catalytic site, can induce such as profound change in enzyme activity. To address this question, we performed unbiased ...
ethanol + NAD+ = 2,3-butanediol + NADH) is an unfavorable reaction under standard state conditions (ΔG’m = 33 kJ/mol, where ΔG’mis the free energy change at 1 mM standard state and pH 7.0)18. Nevertheless, the purge valve system did prove effective in these...
It is made clear why certain species (water, H + in buffered systems) may be ignored in calculating the affinity (negative free energy change) of a chemical reaction. The equilibrium constant is expressed in terms of generalized phase integrals or partition functions....
In subject area:Chemistry Linear free-energy relationships (LFERs) may be regarded as linear relationships between the logarithms of the rate or equilibrium constants for one reaction series and those for a second reaction series subjected to the same variation in reactant structure or reaction condi...
