And our heat of reaction or enthalpy of reaction is defined as the enthalpy at constant pressure. 我们的反应热,或反映,的焓被定义为恒压,等温。
The thermodynamic standard enthalpy change Δ H~ o_m and entropy change Δ S~ o_m of adsorption reaction were both below zero, suggesting that adsorption reaction was an exothermic one and tended to be more in ordered state. 吸附反应的焓变ΔHom和熵变ΔSom均小于零,为放热反应,反应向更有序状态进行;
The model calculation shows that the heating of carrier gas and enthalpy of slag-forming reaction have little contribution to the temperture drop of steel. 模型计算结果表明:对喷吹气体加热以及成渣反应导致的钢液温降基本上可以忽略;
The enthalpy and the Gibbs free energy of the possible reaction during the oxidation process were calculated. 在高温抗氧化机理部分中首先从热力学上计算了氧化过程中各反应的生成焓和吉布斯自由能;
The effect of temperature on the reaction was studied through thermodynamics, and the change of entropy, enthalpy and free energy of the reaction were calculated. 采用热力学方法研究了温度对包合反应的影响,计算了包合过程的熵变、焓变及自由能变化;
Secondly, the enthalpy of elementary substance under standard state is defined as the criterion of component enthalpy, thus reaction heat is no longer needed in energy balance. 其次,热量衡算时,将标准状态下单质的焓定义为所有组分的基准焓,不再需要反应热数据。
However, the viscosity of diluted solution will not change much with pH value that increases as temperature goes up. The enthalpy of ionization reaction of the copolymer △ H is 198. 36 kJ/ mol. 温度升高,稀溶液pH值增加,共聚物电离反应的热焓△Hion为198.36kJ/mol;
Determination of Enthalpy Change of Reaction of Formation, Molar Heat Capacity and Constant-Volume Combustion Energy of the Ternary Solid Complex Lu ( Et2dtc) 3 ( phen) Lu(Et2dtc)3(phen)的生成反应焓变、摩尔热容和恒容燃烧能测定(英文)
