SAT 2 the equilibrium constant of a reaction changes as the concentration of the reactants changes.为什么是错的,反应物浓度不影响平衡吗?题干是醋酸的电离平衡.STATEMENT II解释是Changes in the concentrations of reactants and products do not affect the value of the equilibrium constant; if the ...
In this paper, we consider a reaction-diffusion SIS epidemic model with saturated incidence rate in advective heterogeneous environments. The existence of the endemic equilibrium (EE) is established when the basic reproduction number is greater than one. We further investigate the effects of diffusion...
The equilibrium of the heterogeneous reaction between dissolved sodium sulfide and biologically produced sulfur particles has been studied. Biologically produced sulfur was obtained from a bioreactor of a hydrogen sulfide removal process in which the dominating organism is Thiobacillus sp. W5. Detailed kno...

Complete conversion of glucose into fructose is impossible due to the thermodynamic equilibrium of the reaction. Typically, a mixture of 42% fructose and 52% glucose is obtained by glucose isomerase2. In order to increase the concentration of fructose, separation and enrichment of fructose from the...
When a chemical reaction reaches equilibrium, the rate of the forward reaction is ___ the rate of the reverse reaction. A. greater than B. less than C. equal to D. not related to 相关知识点: 试题来源: 解析 C。在化学平衡状态下,正反应速率等于逆反应速率。选项 A“greater than”表示...
