読みましたが、全体的に理解出来ません。英語で理解出来なかったので多分、全文和訳しても理解出来ません。 なので、この写真に載っていることを分かりやすく教えていただきたいです🙇🏻‍♀️

Free energy changes determine if a reaction is endothermic or exothermic. Processes in nature are driven in two directions: toward least MAIN IDEA enthalpy and toward greatest entropy. When these two oppose each other, the dominant factor determines th direction of change. As a way to predict which factor will dominate fora given system, a function has been defined to relate the enthalpy and entropy factors at a given temperature tropy and constant pressure. This combined enthalpy-entropy function is callepd t free energy, G, of the system; it is also called Gibbs free energy. This function simultaneously assesses the tendencies for enthalpy and entropy to change. Natural processes proceed in the direction that lowersthefree energy of a system. Only the change in free energy can be measured. It can be defined in terms of changes in enthalpy and entropy. At a constant pressure and temperature, the free-energy change, AG, of a system is defined as the difference between the change in enthalpy, AH, and the product of the Kelvin temperature and the entropy change, which is defined as TAS. Free Energy Change AGO= AH°- TASO Note that this expression is for substances in their standard states. The product TAS and the quantities AG and AHhave the same umor usually kJ. The units of AS for use in this equation are usually N If AG<0, the reaction is spontaneous. AH and AS in the free-energy equation can have positive or negative values. This leads to four possible combinations of terms.

下線部のandが結ぶかたまりがbe quite~とnot speak ~だと思ったのですが、回答が違いました。理由が知りたいです。

次の英文を読んで、下記の問いに答えなさい。 Everyone knows what is supposed to happen when two English people who have never met before come face to face ina train-they start talking about the weather. In some cases this may simply be because they happen to find the subject interesting. Most people, though, are not particularly interested in analyses of climatic conditions, so there must be other reasons for conversations of this kind. ,One explanation is that it can often be quite embarrassing to be alone in the company of someone you are not acquainted with and not speak to them. If no conversation takes place the atmosphere can become rather , strained. However, by talking to the other person about some neutral topic like the weather, it is possible to strike up a relationship without actually having to say very much. Train conversations of this kind-and they do happen, although not of course as often as the popular myth supposes-are a good example of the sort of important social function that is often fulfilled by language. Language is not simply a means of communicating information-about the weather or any other subject. It is also a very important means of establishing and maintaining relationships with other people. Probably the most important thing about the conversation between our two English people is not the words they are using, but the fact that they are talking at all.
