thirteen an equal opposite reaction

Based on the current information, I don't know what you want to ask about the irreversible reaction with the same gas volume before and after the reaction, such as the characteristics of the equilibrium movement, the judgment method, or other related concepts? If it was about the characteristics of the equilibrium shift, for a irreversible reaction with the same gas volume before and after the reaction (that is, the number of gas molecules does not change), changing the pressure, the concentration of the reacting gas and the generated gas will change to the same extent, but the concentration quotient will not change. The positive reaction and the reverse reaction rate will change to the same extent, but they will still be equal, and the equilibrium will not move. It should be noted that the above law is for reactions involving gases. Solid or liquid substances are less affected by pressure. When there is only solid or liquid substance in the equilibrium mixture, the pressure equilibrium generally does not move. If it's a question about other aspects, please clarify it so that you can answer it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The heat of reaction refers to the heat released or absorbed by a chemical reaction under constant pressure and without any non-expansion work. If the temperature of the product returns to the initial temperature of the reagent, the system will release or absorb heat. The heat of formation was a form of chemical reaction heat. Therefore, the heat of formation of the product was only a special case of the heat of reaction, and the two were not equal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The change in the temperature (? H) was equal to the total bond energy of the reagent minus the total bond energy of the product. In a chemical reaction, the breaking of an old bond required the absorption of energy (corresponding to the bond energy of the reagent), and the formation of a new bond would release energy (corresponding to the bond energy of the product). The change in the energetics reflected the change in the energy during the reaction. The difference in the bond energies could be calculated to obtain the change in the energetics of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For a reaction where the gas volume before and after the reaction was equal, the following problems were explained: 1. ** Effect of pressure on reaction rate **: The method of increasing or decreasing pressure usually has little effect on the reaction rate. For example, for an equal-volume reaction such as <anno data-annotation-id ="cdf3c02 - 4c02 - 4c50-a110-b112333333"></anno>, changing the pressure would not significantly change the speed of the reaction. 2. ** Shift of chemical equilibrium **: According to Le Chatelier's principle, when the pressure changes, the reaction equilibrium will not shift due to the change in pressure. Because the volume of the gas did not change before and after the reaction, the pressure change had the same effect on the forward and reverse reaction rates, so the equilibrium state would not be broken. However, this did not mean that the reaction would not be affected by other factors, such as temperature, concentration, and catalyst. The reaction could only proceed smoothly under a certain temperature, pressure, and catalyst. The equal-volume reaction was relatively special in terms of controlling the reaction conditions and needed to consider a variety of factors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The correct way to write it was to be blessed. The phrase " great fortune equals the sky " was a commonly used blessing in traditional Chinese festivals. It meant that great fortune had emerged, and good luck and happiness were common. Among them,"Hong" was a word that emphasized degree,"Fu" referred to good prosperity, yearning, and expectations, and "Qi" referred to everyone obtaining the same blessing. Fortune Rivalling Heaven and Great Fortune Rivalling Heaven had the same meaning. They both meant that one's luck was as good as the heavens and that one's luck was extremely great.
