即同一元素的價(jià)態(tài)由反應(yīng)前的高價(jià)和低價(jià)都轉(zhuǎn)化成反應(yīng)以后的中間價(jià)態(tài),,在化學(xué)反應(yīng)中元素的價(jià)態(tài)變化有個(gè)規(guī)律:只靠攏,,不交叉。因此元素的高價(jià)和低價(jià)都只能向中間靠攏,。歸中反應(yīng)和歧化反應(yīng)是兩個(gè)‘相反’的過(guò)程,,這兩種反應(yīng)都一定是氧化還原反應(yīng)。
有機(jī)反應(yīng):指以碳原子化合物為主的各種反應(yīng),。
氧化還原反應(yīng):指兩化合物間的電子轉(zhuǎn)移(如:?jiǎn)稳〈磻?yīng)和燃燒反應(yīng))
燃燒反應(yīng)(初中化學(xué)書(shū)上也叫氧化反應(yīng)):指物質(zhì)和氧氣的反應(yīng),。根據(jù)吉布斯自由能判據(jù),當(dāng)ΔrGm=0時(shí),反應(yīng)達(dá)zui大限度,,處于平衡狀態(tài)?;瘜W(xué)平衡的建立是以可逆反應(yīng)為前提的,。可逆反應(yīng)是指在同一條件下既能正向進(jìn)行又能逆向進(jìn)行的反應(yīng),。絕大多數(shù)化學(xué)反應(yīng)都具有可逆性,,都可在不同程度上達(dá)到平衡。
從動(dòng)力學(xué)角度看,,反應(yīng)開(kāi)始時(shí),,反應(yīng)物濃度較大,產(chǎn)物濃度較小,,所以正反應(yīng)速率大于逆反應(yīng)速率,。隨著反應(yīng)的進(jìn)行,反應(yīng)物濃度不斷減小,,產(chǎn)物濃度不斷增大,,所以正反應(yīng)速率不斷減小,逆反應(yīng)速率不斷增大,。當(dāng)正,、逆反應(yīng)速率相等時(shí),系統(tǒng)中各物質(zhì)的濃度不再發(fā)生變化,,反應(yīng)達(dá)到了平衡,。
19世紀(jì)50-60年代,熱力學(xué)的基本規(guī)律已明確起來(lái),,但是一些熱力學(xué)概念還比較模糊,,數(shù)字處理很煩瑣,不能用來(lái)解決稍微復(fù)雜一點(diǎn)的問(wèn)題,,例如化學(xué)反應(yīng)的方向問(wèn)題,。當(dāng)時(shí),大多數(shù)化學(xué)家正致力于有機(jī)化學(xué)的研究,,也有一些人試圖解決化學(xué)反應(yīng)的方向問(wèn)題,。這種努力除了質(zhì)量作用定律之外,還有其他一些人試圖從別的角度進(jìn)行反應(yīng)方向的探索,,其中已有人提出了一些經(jīng)驗(yàn)性的規(guī)律,。在這一時(shí)期,丹麥人湯姆生和貝特羅試圖從化學(xué)反應(yīng)的熱效應(yīng)來(lái)解釋化學(xué)反應(yīng)的方向性,。他們認(rèn)為,,反應(yīng)熱是反應(yīng)物化學(xué)親合力的量度,每個(gè)簡(jiǎn)單或復(fù)雜的純化學(xué)性的作用,都伴隨著熱量的產(chǎn)生,。貝特羅更為明確地闡述了與這相同的觀點(diǎn),,并稱之為“zui大功原理”,他認(rèn)為任何一種無(wú)外部能量影響的純化學(xué)變化,,向著產(chǎn)生釋放出zui大能量的物質(zhì)的方向進(jìn)行,。雖然這時(shí)他發(fā)現(xiàn)了一些吸熱反應(yīng)也可以自發(fā)地進(jìn)行,但他卻主觀地假定其中伴有放熱的物理過(guò)程,。這一錯(cuò)誤的論斷在30年代終于被他承認(rèn)了,,這時(shí)他才將“zui大功原理”的應(yīng)用范圍限制在固體間的反應(yīng)上,并提出了實(shí)際上是“自由焓”的化學(xué)熱的概念,。

That is, the valence of the same element is converted into the intermediate valence state after the reaction by both the high price and the low price before the reaction, and the valence state of the element in the chemical reaction has a law that only the distance and the distance are not crossed. Therefore, the elements of high and low prices can only move closer to the middle. Both centralization and disproportionation are two 'opposite' processes, and both must be redox reactions.
Organic reaction: refers to a variety of carbon-based compounds reaction.
Redox reaction: refers to the electronic transfer between the two compounds (such as: mono-substitution reaction and combustion reaction)
Burning reaction (junior high school chemistry book, also known as oxidation reaction): refers to the reaction of substances and oxygen. According to the Gibbs free energy criterion, when ΔrGm = 0, the reaction reaches the maximum, in a state of equilibrium. The establishment of chemical equilibrium is based on the reversible reaction. Reversible reaction refers to both under the same conditions can forward and reverse the reaction. The vast majority of chemical reactions are reversible, can be balanced to varying degrees.
From the kinetic point of view, at the beginning of the reaction, the reactant concentration is larger and the product concentration is smaller, so the positive reaction rate is greater than the reverse reaction rate. With the progress of the reaction, the reactant concentration continuously decreases and the product concentration continuously increases, so the positive reaction rate continuously decreases and the reverse reaction rate continuously increases. When the positive and the reverse reaction rate are equal, the concentration of each substance in the system no longer changes, the reaction has reached a balance.
The basic laws of thermodynamics have been clarified in the 1950s and 1960s. However, some of the concepts of thermodynamics are still vague. Digital processing is cumbersome and can not be used to solve slightly complicated problems such as the direction of chemical reactions. At the time, most chemists were working on organic chemistry and others were trying to solve the problem of chemical reactions. In addition to the law of mass action, this effort attempts to explore the direction of the reaction from other perspectives, some of which have been put forward by some of the empirical laws. During this period, the Danish Thomson and Bertolu tried to explain the direction of the chemical reaction from the thermal effect of the chemical reaction. They think that the heat of reaction is a measure of the chemical affinity of the reactants and that each simple or complex purely chemical action is accompanied by the generation of heat. Bertolu articulated this same point more explicitly, calling it the "principle of maximum work," in the belief that any purely chemical change without the influence of external energy is directed towards the production of the substance that releases the greatest amount of energy . Although at this time he found that some endothermic reactions could spontaneously proceed, he subjectively assumed that there was an exothermic physical process. This false assertion was eventually accepted by him in the 1930s when he limited the application of the "greatest work principle" to the reaction between solids and proposed the notion of "chemical free heat" .
